    Description: Meiotic recombination events cluster into narrow segments of the genome, defined as hotspots. Here, we demonstrate that a major player for hotspot specification is the Prdm9 gene. First, two mouse strains that differ in hotspot usage are polymorphic for the zinc finger DNA binding array of PRDM9. Second, the human consensus PRDM9 allele is predicted to recognize the 13-mer motif enriched at human hotspots; this DNA binding specificity is verified by in vitro studies. Third, allelic variants of PRDM9 zinc fingers are significantly associated with variability in genome-wide hotspot usage among humans. Our results provide a molecular basis for the distribution of meiotic recombination in mammals, in which the binding of PRDM9 to specific DNA sequences targets the initiation of recombination at specific locations in the genome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4295902/" 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/PMC4295902/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baudat, F -- Buard, J -- Grey, C -- Fledel-Alon, A -- Ober, C -- Przeworski, M -- Coop, G -- de Massy, B -- 03S1/PHS HHS/ -- GM83098/GM/NIGMS NIH HHS/ -- HD21244/HD/NICHD NIH HHS/ -- HL085197/HL/NHLBI NIH HHS/ -- R01 GM083098/GM/NIGMS NIH HHS/ -- R01 HD021244/HD/NICHD NIH HHS/ -- R01 HL085197/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Feb 12;327(5967):836-40. doi: 10.1126/science.1183439.

    Description: The mammalian cytoskeletal proteins beta- and gamma-actin are highly homologous, but only beta-actin is amino-terminally arginylated in vivo, which regulates its function. We examined the metabolic fate of exogenously expressed arginylated and nonarginylated actin isoforms. Arginylated gamma-actin, unlike beta-, was highly unstable and was selectively ubiquitinated and degraded in vivo. This instability was regulated by the differences in the nucleotide coding sequence between the two actin isoforms, which conferred different translation rates. gamma-actin was translated more slowly than beta-actin, and this slower processing resulted in the exposure of a normally hidden lysine residue for ubiquitination, leading to the preferential degradation of gamma-actin upon arginylation. This degradation mechanism, coupled to nucleotide coding sequence, may regulate protein arginylation in vivo.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2941909/" 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/PMC2941909/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Fangliang -- Saha, Sougata -- Shabalina, Svetlana A -- Kashina, Anna -- 5R01HL084419/HL/NHLBI NIH HHS/ -- R01 HL084419/HL/NHLBI NIH HHS/ -- R01 HL084419-03/HL/NHLBI NIH HHS/ -- R01 HL084419-03S1/HL/NHLBI NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 17;329(5998):1534-7. doi: 10.1126/science.1191701.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Animal Biology, School of Veterinary Medicine, University of Pennsylvania, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20847274" target="_blank"〉PubMed〈/a〉

    Description: Many oomycete and fungal plant pathogens are obligate biotrophs, which extract nutrients only from living plant tissue and cannot grow apart from their hosts. Although these pathogens cause substantial crop losses, little is known about the molecular basis or evolution of obligate biotrophy. Here, we report the genome sequence of the oomycete Hyaloperonospora arabidopsidis (Hpa), an obligate biotroph and natural pathogen of Arabidopsis thaliana. In comparison with genomes of related, hemibiotrophic Phytophthora species, the Hpa genome exhibits dramatic reductions in genes encoding (i) RXLR effectors and other secreted pathogenicity proteins, (ii) enzymes for assimilation of inorganic nitrogen and sulfur, and (iii) proteins associated with zoospore formation and motility. These attributes comprise a genomic signature of evolution toward obligate biotrophy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3971456/" 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/PMC3971456/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baxter, Laura -- Tripathy, Sucheta -- Ishaque, Naveed -- Boot, Nico -- Cabral, Adriana -- Kemen, Eric -- Thines, Marco -- Ah-Fong, Audrey -- Anderson, Ryan -- Badejoko, Wole -- Bittner-Eddy, Peter -- Boore, Jeffrey L -- Chibucos, Marcus C -- Coates, Mary -- Dehal, Paramvir -- Delehaunty, Kim -- Dong, Suomeng -- Downton, Polly -- Dumas, Bernard -- Fabro, Georgina -- Fronick, Catrina -- Fuerstenberg, Susan I -- Fulton, Lucinda -- Gaulin, Elodie -- Govers, Francine -- Hughes, Linda -- Humphray, Sean -- Jiang, Rays H Y -- Judelson, Howard -- Kamoun, Sophien -- Kyung, Kim -- Meijer, Harold -- Minx, Patrick -- Morris, Paul -- Nelson, Joanne -- Phuntumart, Vipa -- Qutob, Dinah -- Rehmany, Anne -- Rougon-Cardoso, Alejandra -- Ryden, Peter -- Torto-Alalibo, Trudy -- Studholme, David -- Wang, Yuanchao -- Win, Joe -- Wood, Jo -- Clifton, Sandra W -- Rogers, Jane -- Van den Ackerveken, Guido -- Jones, Jonathan D G -- McDowell, John M -- Beynon, Jim -- Tyler, Brett M -- 079643/Wellcome Trust/United Kingdom -- BB/C509123/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E007120/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E024815/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E024882/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/F0161901/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/G015244/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- EP/F500025/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- T12144/Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1549-51. doi: 10.1126/science.1195203.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Life Sciences, Warwick University, Wellesbourne, CV35 9EF, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21148394" target="_blank"〉PubMed〈/a〉

    Description: Fanconi anemia (FA) is caused by mutations in 13 Fanc genes and renders cells hypersensitive to DNA interstrand cross-linking (ICL) agents. A central event in the FA pathway is mono-ubiquitylation of the FANCI-FANCD2 (ID) protein complex. Here, we characterize a previously unrecognized nuclease, Fanconi anemia-associated nuclease 1 (FAN1), that promotes ICL repair in a manner strictly dependent on its ability to accumulate at or near sites of DNA damage and that relies on mono-ubiquitylation of the ID complex. Thus, the mono-ubiquitylated ID complex recruits the downstream repair protein FAN1 and facilitates the repair of DNA interstrand cross-links.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Ting -- Ghosal, Gargi -- Yuan, Jingsong -- Chen, Junjie -- Huang, Jun -- New York, N.Y. -- Science. 2010 Aug 6;329(5992):693-6. doi: 10.1126/science.1192656.

    Description: The genetics of sex determination remain mysterious in many organisms, including some that are otherwise well studied. Here we report the discovery and analysis of the mating-type locus of the model organism Dictyostelium discoideum. Three forms of a single genetic locus specify this species' three mating types: two versions of the locus are entirely different in sequence, and the third resembles a composite of the other two. Single, unrelated genes are sufficient to determine two of the mating types, whereas homologs of both these genes are required in the composite type. The key genes encode polypeptides that possess no recognizable similarity to established protein families. Sex determination in the social amoebae thus appears to use regulators that are unrelated to any others currently known.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3648785/" 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/PMC3648785/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bloomfield, Gareth -- Skelton, Jason -- Ivens, Alasdair -- Tanaka, Yoshimasa -- Kay, Robert R -- 06724/Wellcome Trust/United Kingdom -- 076964/Wellcome Trust/United Kingdom -- MC_U105115237/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1533-6. doi: 10.1126/science.1197423.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Laboratory of Molecular Biology, Hills Road, Cambridge CB2 0QH, UK. garethb@mrc-lmb.cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21148389" target="_blank"〉PubMed〈/a〉

    Description: During embryonic development, many organs form by extensive branching of epithelia through the formation of clefts and buds. In cleft formation, buds are delineated by the conversion of epithelial cell-cell adhesions to cell-matrix adhesions, but the mechanisms of cleft formation are not clear. We have identified Btbd7 as a dynamic regulator of branching morphogenesis. Btbd7 provides a mechanistic link between the extracellular matrix and cleft propagation through its highly focal expression leading to local regulation of Snail2 (Slug), E-cadherin, and epithelial cell motility. Inhibition experiments show that Btbd7 is required for branching of embryonic mammalian salivary glands and lungs. Hence, Btbd7 is a regulatory gene that promotes epithelial tissue remodeling and formation of branched organs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3412157/" 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/PMC3412157/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Onodera, Tomohiro -- Sakai, Takayoshi -- Hsu, Jeff Chi-feng -- Matsumoto, Kazue -- Chiorini, John A -- Yamada, Kenneth M -- ZIA DE000525-20/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Jul 30;329(5991):562-5. doi: 10.1126/science.1191880.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Cell and Developmental Biology, National Institute of Dental and Craniofacial Research, National Institutes of Health, Bethesda, MD 20892-4370, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20671187" target="_blank"〉PubMed〈/a〉
