Description: Using next-generation sequencing technology alone, we have successfully generated and assembled a draft sequence of the giant panda genome. The assembled contigs (2.25 gigabases (Gb)) cover approximately 94% of the whole genome, and the remaining gaps (0.05 Gb) seem to contain carnivore-specific repeats and tandem repeats. Comparisons with the dog and human showed that the panda genome has a lower divergence rate. The assessment of panda genes potentially underlying some of its unique traits indicated that its bamboo diet might be more dependent on its gut microbiome than its own genetic composition. We also identified more than 2.7 million heterozygous single nucleotide polymorphisms in the diploid genome. Our data and analyses provide a foundation for promoting mammalian genetic research, and demonstrate the feasibility for using next-generation sequencing technologies for accurate, cost-effective and rapid de novo assembly of large eukaryotic genomes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3951497/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3951497/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Ruiqiang -- Fan, Wei -- Tian, Geng -- Zhu, Hongmei -- He, Lin -- Cai, Jing -- Huang, Quanfei -- Cai, Qingle -- Li, Bo -- Bai, Yinqi -- Zhang, Zhihe -- Zhang, Yaping -- Wang, Wen -- Li, Jun -- Wei, Fuwen -- Li, Heng -- Jian, Min -- Li, Jianwen -- Zhang, Zhaolei -- Nielsen, Rasmus -- Li, Dawei -- Gu, Wanjun -- Yang, Zhentao -- Xuan, Zhaoling -- Ryder, Oliver A -- Leung, Frederick Chi-Ching -- Zhou, Yan -- Cao, Jianjun -- Sun, Xiao -- Fu, Yonggui -- Fang, Xiaodong -- Guo, Xiaosen -- Wang, Bo -- Hou, Rong -- Shen, Fujun -- Mu, Bo -- Ni, Peixiang -- Lin, Runmao -- Qian, Wubin -- Wang, Guodong -- Yu, Chang -- Nie, Wenhui -- Wang, Jinhuan -- Wu, Zhigang -- Liang, Huiqing -- Min, Jiumeng -- Wu, Qi -- Cheng, Shifeng -- Ruan, Jue -- Wang, Mingwei -- Shi, Zhongbin -- Wen, Ming -- Liu, Binghang -- Ren, Xiaoli -- Zheng, Huisong -- Dong, Dong -- Cook, Kathleen -- Shan, Gao -- Zhang, Hao -- Kosiol, Carolin -- Xie, Xueying -- Lu, Zuhong -- Zheng, Hancheng -- Li, Yingrui -- Steiner, Cynthia C -- Lam, Tommy Tsan-Yuk -- Lin, Siyuan -- Zhang, Qinghui -- Li, Guoqing -- Tian, Jing -- Gong, Timing -- Liu, Hongde -- Zhang, Dejin -- Fang, Lin -- Ye, Chen -- Zhang, Juanbin -- Hu, Wenbo -- Xu, Anlong -- Ren, Yuanyuan -- Zhang, Guojie -- Bruford, Michael W -- Li, Qibin -- Ma, Lijia -- Guo, Yiran -- An, Na -- Hu, Yujie -- Zheng, Yang -- Shi, Yongyong -- Li, Zhiqiang -- Liu, Qing -- Chen, Yanling -- Zhao, Jing -- Qu, Ning -- Zhao, Shancen -- Tian, Feng -- Wang, Xiaoling -- Wang, Haiyin -- Xu, Lizhi -- Liu, Xiao -- Vinar, Tomas -- Wang, Yajun -- Lam, Tak-Wah -- Yiu, Siu-Ming -- Liu, Shiping -- Zhang, Hemin -- Li, Desheng -- Huang, Yan -- Wang, Xia -- Yang, Guohua -- Jiang, Zhi -- Wang, Junyi -- Qin, Nan -- Li, Li -- Li, Jingxiang -- Bolund, Lars -- Kristiansen, Karsten -- Wong, Gane Ka-Shu -- Olson, Maynard -- Zhang, Xiuqing -- Li, Songgang -- Yang, Huanming -- Wang, Jian -- Wang, Jun -- R01 HG003229/HG/NHGRI NIH HHS/ -- R01 HG003229-05/HG/NHGRI NIH HHS/ -- England -- Nature. 2010 Jan 21;463(7279):311-7. doi: 10.1038/nature08696.

Description: Here we present the first diploid genome sequence of an Asian individual. The genome was sequenced to 36-fold average coverage using massively parallel sequencing technology. We aligned the short reads onto the NCBI human reference genome to 99.97% coverage, and guided by the reference genome, we used uniquely mapped reads to assemble a high-quality consensus sequence for 92% of the Asian individual's genome. We identified approximately 3 million single-nucleotide polymorphisms (SNPs) inside this region, of which 13.6% were not in the dbSNP database. Genotyping analysis showed that SNP identification had high accuracy and consistency, indicating the high sequence quality of this assembly. We also carried out heterozygote phasing and haplotype prediction against HapMap CHB and JPT haplotypes (Chinese and Japanese, respectively), sequence comparison with the two available individual genomes (J. D. Watson and J. C. Venter), and structural variation identification. These variations were considered for their potential biological impact. Our sequence data and analyses demonstrate the potential usefulness of next-generation sequencing technologies for personal genomics.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2716080/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2716080/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Jun -- Wang, Wei -- Li, Ruiqiang -- Li, Yingrui -- Tian, Geng -- Goodman, Laurie -- Fan, Wei -- Zhang, Junqing -- Li, Jun -- Zhang, Juanbin -- Guo, Yiran -- Feng, Binxiao -- Li, Heng -- Lu, Yao -- Fang, Xiaodong -- Liang, Huiqing -- Du, Zhenglin -- Li, Dong -- Zhao, Yiqing -- Hu, Yujie -- Yang, Zhenzhen -- Zheng, Hancheng -- Hellmann, Ines -- Inouye, Michael -- Pool, John -- Yi, Xin -- Zhao, Jing -- Duan, Jinjie -- Zhou, Yan -- Qin, Junjie -- Ma, Lijia -- Li, Guoqing -- Yang, Zhentao -- Zhang, Guojie -- Yang, Bin -- Yu, Chang -- Liang, Fang -- Li, Wenjie -- Li, Shaochuan -- Li, Dawei -- Ni, Peixiang -- Ruan, Jue -- Li, Qibin -- Zhu, Hongmei -- Liu, Dongyuan -- Lu, Zhike -- Li, Ning -- Guo, Guangwu -- Zhang, Jianguo -- Ye, Jia -- Fang, Lin -- Hao, Qin -- Chen, Quan -- Liang, Yu -- Su, Yeyang -- San, A -- Ping, Cuo -- Yang, Shuang -- Chen, Fang -- Li, Li -- Zhou, Ke -- Zheng, Hongkun -- Ren, Yuanyuan -- Yang, Ling -- Gao, Yang -- Yang, Guohua -- Li, Zhuo -- Feng, Xiaoli -- Kristiansen, Karsten -- Wong, Gane Ka-Shu -- Nielsen, Rasmus -- Durbin, Richard -- Bolund, Lars -- Zhang, Xiuqing -- Li, Songgang -- Yang, Huanming -- Wang, Jian -- 077192/Wellcome Trust/United Kingdom -- R01 HG003229/HG/NHGRI NIH HHS/ -- R01 HG003229-04/HG/NHGRI NIH HHS/ -- England -- Nature. 2008 Nov 6;456(7218):60-5. doi: 10.1038/nature07484.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Beijing Genomics Institute at Shenzhen, Shenzhen 518000, China. wangj@genomics.org.cn〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18987735" target="_blank"〉PubMed〈/a〉

Description: The great Sumatra-Andaman earthquake and tsunami of 2004 was a dramatic reminder of the importance of understanding the seismic and tsunami hazards of subduction zones. In March 2005, the Sunda megathrust ruptured again, producing an event of moment magnitude (M(w)) 8.6 south of the 2004 rupture area, which was the site of a similar event in 1861 (ref. 6). Concern was then focused on the Mentawai area, where large earthquakes had occurred in 1797 (M(w) = 8.8) and 1833 (M(w) = 9.0). Two earthquakes, one of M(w) = 8.4 and, twelve hours later, one of M(w) = 7.9, indeed occurred there on 12 September 2007. Here we show that these earthquakes ruptured only a fraction of the area ruptured in 1833 and consist of distinct asperities within a patch of the megathrust that had remained locked in the interseismic period. This indicates that the same portion of a megathrust can rupture in different patterns depending on whether asperities break as isolated seismic events or cooperate to produce a larger rupture. This variability probably arises from the influence of non-permanent barriers, zones with locally lower pre-stress due to the past earthquakes. The stress state of the portion of the Sunda megathrust that had ruptured in 1833 and 1797 was probably not adequate for the development of a single large rupture in 2007. The moment released in 2007 amounts to only a fraction both of that released in 1833 and of the deficit of moment that had accumulated as a result of interseismic strain since 1833. The potential for a large megathrust event in the Mentawai area thus remains large.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Konca, A Ozgun -- Avouac, Jean-Philippe -- Sladen, Anthony -- Meltzner, Aron J -- Sieh, Kerry -- Fang, Peng -- Li, Zhenhong -- Galetzka, John -- Genrich, Jeff -- Chlieh, Mohamed -- Natawidjaja, Danny H -- Bock, Yehuda -- Fielding, Eric J -- Ji, Chen -- Helmberger, Don V -- England -- Nature. 2008 Dec 4;456(7222):631-5. doi: 10.1038/nature07572.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Tectonics Observatory, Division of Geological and Planetary Sciences, California Institute of Technology, Pasadena, California 91125, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19052626" target="_blank"〉PubMed〈/a〉

Description: Insulin-like growth-factor-binding proteins (IGFBPs) bind to and modulate the actions of insulin-like growth factors (IGFs). Although some of the actions of IGFBPs have been reported to be independent of IGFs, the precise mechanisms of IGF-independent actions of IGFBPs are largely unknown. Here we report a previously unknown function for IGFBP-4 as a cardiogenic growth factor. IGFBP-4 enhanced cardiomyocyte differentiation in vitro, and knockdown of Igfbp4 attenuated cardiomyogenesis both in vitro and in vivo. The cardiogenic effect of IGFBP-4 was independent of its IGF-binding activity but was mediated by the inhibitory effect on canonical Wnt signalling. IGFBP-4 physically interacted with a Wnt receptor, Frizzled 8 (Frz8), and a Wnt co-receptor, low-density lipoprotein receptor-related protein 6 (LRP6), and inhibited the binding of Wnt3A to Frz8 and LRP6. Although IGF-independent, the cardiogenic effect of IGFBP-4 was attenuated by IGFs through IGFBP-4 sequestration. IGFBP-4 is therefore an inhibitor of the canonical Wnt signalling required for cardiogenesis and provides a molecular link between IGF signalling and Wnt signalling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhu, Weidong -- Shiojima, Ichiro -- Ito, Yuzuru -- Li, Zhi -- Ikeda, Hiroyuki -- Yoshida, Masashi -- Naito, Atsuhiko T -- Nishi, Jun-ichiro -- Ueno, Hiroo -- Umezawa, Akihiro -- Minamino, Tohru -- Nagai, Toshio -- Kikuchi, Akira -- Asashima, Makoto -- Komuro, Issei -- England -- Nature. 2008 Jul 17;454(7202):345-9. doi: 10.1038/nature07027.

Description: Water-in-oil-in-water emulsions are examples of double emulsions, in which dispersions of small water droplets within larger oil droplets are themselves dispersed in a continuous aqueous phase. Emulsions occur in many forms of processing and are used extensively by the foods, cosmetics and coatings industries. Because of their compartmentalized internal structure, double emulsions can provide advantages over simple oil-in-water emulsions for encapsulation, such as the ability to carry both polar and non-polar cargos, and improved control over release of therapeutic molecules. The preparation of double emulsions typically requires mixtures of surfactants for stability; the formation of double nanoemulsions, where both inner and outer droplets are under 100 nm, has not yet been achieved. Here we show that water-in-oil-in-water double emulsions can be prepared in a simple process and stabilized over many months using single-component, synthetic amphiphilic diblock copolypeptide surfactants. These surfactants even stabilize droplets subjected to extreme flow, leading to direct, mass production of robust double nanoemulsions that are amenable to nanostructured encapsulation applications in foods, cosmetics and drug delivery.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hanson, Jarrod A -- Chang, Connie B -- Graves, Sara M -- Li, Zhibo -- Mason, Thomas G -- Deming, Timothy J -- England -- Nature. 2008 Sep 4;455(7209):85-8. doi: 10.1038/nature07197.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Bioengineering Department, University of California, Los Angeles, California 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18769436" target="_blank"〉PubMed〈/a〉

Description: A major yet unresolved quest in decoding the human genome is the identification of the regulatory sequences that control the spatial and temporal expression of genes. Distant-acting transcriptional enhancers are particularly challenging to uncover because they are scattered among the vast non-coding portion of the genome. Evolutionary sequence constraint can facilitate the discovery of enhancers, but fails to predict when and where they are active in vivo. Here we present the results of chromatin immunoprecipitation with the enhancer-associated protein p300 followed by massively parallel sequencing, and map several thousand in vivo binding sites of p300 in mouse embryonic forebrain, midbrain and limb tissue. We tested 86 of these sequences in a transgenic mouse assay, which in nearly all cases demonstrated reproducible enhancer activity in the tissues that were predicted by p300 binding. Our results indicate that in vivo mapping of p300 binding is a highly accurate means for identifying enhancers and their associated activities, and suggest that such data sets will be useful to study the role of tissue-specific enhancers in human biology and disease on a genome-wide scale.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2745234/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2745234/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Visel, Axel -- Blow, Matthew J -- Li, Zirong -- Zhang, Tao -- Akiyama, Jennifer A -- Holt, Amy -- Plajzer-Frick, Ingrid -- Shoukry, Malak -- Wright, Crystal -- Chen, Feng -- Afzal, Veena -- Ren, Bing -- Rubin, Edward M -- Pennacchio, Len A -- R01 HG003988/HG/NHGRI NIH HHS/ -- R01 HG003988-02/HG/NHGRI NIH HHS/ -- R01 NS062859/NS/NINDS NIH HHS/ -- R01 NS062859-01/NS/NINDS NIH HHS/ -- England -- Nature. 2009 Feb 12;457(7231):854-8. doi: 10.1038/nature07730.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genomics Division, MS 84-171, Lawrence Berkeley National Laboratory, Berkeley, California 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19212405" target="_blank"〉PubMed〈/a〉

Description: Intracellular ISG15 is an interferon (IFN)-alpha/beta-inducible ubiquitin-like modifier which can covalently bind other proteins in a process called ISGylation; it is an effector of IFN-alpha/beta-dependent antiviral immunity in mice. We previously published a study describing humans with inherited ISG15 deficiency but without unusually severe viral diseases. We showed that these patients were prone to mycobacterial disease and that human ISG15 was non-redundant as an extracellular IFN-gamma-inducing molecule. We show here that ISG15-deficient patients also display unanticipated cellular, immunological and clinical signs of enhanced IFN-alpha/beta immunity, reminiscent of the Mendelian autoinflammatory interferonopathies Aicardi-Goutieres syndrome and spondyloenchondrodysplasia. We further show that an absence of intracellular ISG15 in the patients' cells prevents the accumulation of USP18, a potent negative regulator of IFN-alpha/beta signalling, resulting in the enhancement and amplification of IFN-alpha/beta responses. Human ISG15, therefore, is not only redundant for antiviral immunity, but is a key negative regulator of IFN-alpha/beta immunity. In humans, intracellular ISG15 is IFN-alpha/beta-inducible not to serve as a substrate for ISGylation-dependent antiviral immunity, but to ensure USP18-dependent regulation of IFN-alpha/beta and prevention of IFN-alpha/beta-dependent autoinflammation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4303590/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4303590/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Xianqin -- Bogunovic, Dusan -- Payelle-Brogard, Beatrice -- Francois-Newton, Veronique -- Speer, Scott D -- Yuan, Chao -- Volpi, Stefano -- Li, Zhi -- Sanal, Ozden -- Mansouri, Davood -- Tezcan, Ilhan -- Rice, Gillian I -- Chen, Chunyuan -- Mansouri, Nahal -- Mahdaviani, Seyed Alireza -- Itan, Yuval -- Boisson, Bertrand -- Okada, Satoshi -- Zeng, Lu -- Wang, Xing -- Jiang, Hui -- Liu, Wenqiang -- Han, Tiantian -- Liu, Delin -- Ma, Tao -- Wang, Bo -- Liu, Mugen -- Liu, Jing-Yu -- Wang, Qing K -- Yalnizoglu, Dilek -- Radoshevich, Lilliana -- Uze, Gilles -- Gros, Philippe -- Rozenberg, Flore -- Zhang, Shen-Ying -- Jouanguy, Emmanuelle -- Bustamante, Jacinta -- Garcia-Sastre, Adolfo -- Abel, Laurent -- Lebon, Pierre -- Notarangelo, Luigi D -- Crow, Yanick J -- Boisson-Dupuis, Stephanie -- Casanova, Jean-Laurent -- Pellegrini, Sandra -- 1P01AI076210-01A1/AI/NIAID NIH HHS/ -- 309449/European Research Council/International -- 8UL1TR000043/TR/NCATS NIH HHS/ -- P01 AI076210/AI/NIAID NIH HHS/ -- P01 AI090935/AI/NIAID NIH HHS/ -- P01AI090935/AI/NIAID NIH HHS/ -- R00 AI106942/AI/NIAID NIH HHS/ -- R00AI106942-02/AI/NIAID NIH HHS/ -- R01 AI035237/AI/NIAID NIH HHS/ -- R37 AI095983/AI/NIAID NIH HHS/ -- R37AI095983/AI/NIAID NIH HHS/ -- U19 AI083025/AI/NIAID NIH HHS/ -- U19AI083025/AI/NIAID NIH HHS/ -- UL1 TR000043/TR/NCATS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 Jan 1;517(7532):89-93. doi: 10.1038/nature13801.

Description: Although CRISPR-Cas9 nucleases are widely used for genome editing, the range of sequences that Cas9 can recognize is constrained by the need for a specific protospacer adjacent motif (PAM). As a result, it can often be difficult to target double-stranded breaks (DSBs) with the precision that is necessary for various genome-editing applications. The ability to engineer Cas9 derivatives with purposefully altered PAM specificities would address this limitation. Here we show that the commonly used Streptococcus pyogenes Cas9 (SpCas9) can be modified to recognize alternative PAM sequences using structural information, bacterial selection-based directed evolution, and combinatorial design. These altered PAM specificity variants enable robust editing of endogenous gene sites in zebrafish and human cells not currently targetable by wild-type SpCas9, and their genome-wide specificities are comparable to wild-type SpCas9 as judged by GUIDE-seq analysis. In addition, we identify and characterize another SpCas9 variant that exhibits improved specificity in human cells, possessing better discrimination against off-target sites with non-canonical NAG and NGA PAMs and/or mismatched spacers. We also find that two smaller-size Cas9 orthologues, Streptococcus thermophilus Cas9 (St1Cas9) and Staphylococcus aureus Cas9 (SaCas9), function efficiently in the bacterial selection systems and in human cells, suggesting that our engineering strategies could be extended to Cas9s from other species. Our findings provide broadly useful SpCas9 variants and, more importantly, establish the feasibility of engineering a wide range of Cas9s with altered and improved PAM specificities.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4540238/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4540238/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kleinstiver, Benjamin P -- Prew, Michelle S -- Tsai, Shengdar Q -- Topkar, Ved V -- Nguyen, Nhu T -- Zheng, Zongli -- Gonzales, Andrew P W -- Li, Zhuyun -- Peterson, Randall T -- Yeh, Jing-Ruey Joanna -- Aryee, Martin J -- Joung, J Keith -- DP1 GM105378/DP/NCCDPHP CDC HHS/ -- DP1 GM105378/GM/NIGMS NIH HHS/ -- R01 GM088040/GM/NIGMS NIH HHS/ -- R01 GM107427/GM/NIGMS NIH HHS/ -- England -- Nature. 2015 Jul 23;523(7561):481-5. doi: 10.1038/nature14592.

Direct mapping of chromatin modification marks and transcriptional factor binding sites genome-wide has successfully identified specific subtypes of regulatory elements. In Drosophila several pioneering studies have provided genome-wide identification of Polycomb response elements, chromatin states, transcription factor binding sites, RNA polymerase II regulation and insulator elements; however, comprehensive annotation of the regulatory genome remains a significant challenge. Here we describe results from the modENCODE cis-regulatory annotation project. We produced a map of the Drosophila melanogaster regulatory genome on the basis of more than 300 chromatin immunoprecipitation data sets for eight chromatin features, five histone deacetylases and thirty-eight site-specific transcription factors at different stages of development. Using these data we inferred more than 20,000 candidate regulatory elements and validated a subset of predictions for promoters, enhancers and insulators in vivo. We identified also nearly 2,000 genomic regions of dense transcription factor binding associated with chromatin activity and accessibility. We discovered hundreds of new transcription factor co-binding relationships and defined a transcription factor network with over 800 potential regulatory relationships.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3179250/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3179250/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Negre, Nicolas -- Brown, Christopher D -- Ma, Lijia -- Bristow, Christopher Aaron -- Miller, Steven W -- Wagner, Ulrich -- Kheradpour, Pouya -- Eaton, Matthew L -- Loriaux, Paul -- Sealfon, Rachel -- Li, Zirong -- Ishii, Haruhiko -- Spokony, Rebecca F -- Chen, Jia -- Hwang, Lindsay -- Cheng, Chao -- Auburn, Richard P -- Davis, Melissa B -- Domanus, Marc -- Shah, Parantu K -- Morrison, Carolyn A -- Zieba, Jennifer -- Suchy, Sarah -- Senderowicz, Lionel -- Victorsen, Alec -- Bild, Nicholas A -- Grundstad, A Jason -- Hanley, David -- MacAlpine, David M -- Mannervik, Mattias -- Venken, Koen -- Bellen, Hugo -- White, Robert -- Gerstein, Mark -- Russell, Steven -- Grossman, Robert L -- Ren, Bing -- Posakony, James W -- Kellis, Manolis -- White, Kevin P -- F32 GM074364/GM/NIGMS NIH HHS/ -- F32 GM074364-01/GM/NIGMS NIH HHS/ -- F32 GM074364-02/GM/NIGMS NIH HHS/ -- P50 GM081892/GM/NIGMS NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01 HG004037-04/HG/NHGRI NIH HHS/ -- RC2 HG005639/HG/NHGRI NIH HHS/ -- RC2 HG005639-02/HG/NHGRI NIH HHS/ -- U01 HG004264/HG/NHGRI NIH HHS/ -- U01 HG004279/HG/NHGRI NIH HHS/ -- U01HG004264/HG/NHGRI NIH HHS/ -- England -- Nature. 2011 Mar 24;471(7339):527-31. doi: 10.1038/nature09990.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Genomics and Systems Biology, Department of Human Genetics, The University of Chicago, 900 East 57th Street, Chicago, Illinois 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21430782" target="_blank"〉PubMed〈/a〉

Description: Na(+)-activated K(+) channels are members of the Slo family of large conductance K(+) channels that are widely expressed in the brain, where their opening regulates neuronal excitability. These channels fulfil a number of biological roles and have intriguing biophysical properties, including conductance levels that are ten times those of most other K(+) channels and gating sensitivity to intracellular Na(+). Here we present the structure of a complete Na(+)-activated K(+) channel, chicken Slo2.2, in the Na(+)-free state, determined by cryo-electron microscopy at a nominal resolution of 4.5 angstroms. The channel is composed of a large cytoplasmic gating ring, in which resides the Na(+)-binding site and a transmembrane domain that closely resembles voltage-gated K(+) channels. In the structure, the cytoplasmic domain adopts a closed conformation and the ion conduction pore is also closed. The structure reveals features that can explain the unusually high conductance of Slo channels and how contraction of the cytoplasmic gating ring closes the pore.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hite, Richard K -- Yuan, Peng -- Li, Zongli -- Hsuing, Yichun -- Walz, Thomas -- MacKinnon, Roderick -- GM43949/GM/NIGMS NIH HHS/ -- R01 GM043949/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 Nov 12;527(7577):198-203. doi: 10.1038/nature14958.
