Description: Polyadenylate [poly(A)] polymerase (PAP) catalyzes the addition of a polyadenosine tail to almost all eukaryotic messenger RNAs (mRNAs). The crystal structure of the PAP from Saccharomyces cerevisiae (Pap1) has been solved to 2.6 angstroms, both alone and in complex with 3'-deoxyadenosine triphosphate (3'-dATP). Like other nucleic acid polymerases, Pap1 is composed of three domains that encircle the active site. The arrangement of these domains, however, is quite different from that seen in polymerases that use a template to select and position their incoming nucleotides. The first two domains are functionally analogous to polymerase palm and fingers domains. The third domain is attached to the fingers domain and is known to interact with the single-stranded RNA primer. In the nucleotide complex, two molecules of 3'-dATP are bound to Pap1. One occupies the position of the incoming base, prior to its addition to the mRNA chain. The other is believed to occupy the position of the 3' end of the mRNA primer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bard, J -- Zhelkovsky, A M -- Helmling, S -- Earnest, T N -- Moore, C L -- Bohm, A -- R01 GM57218-01A2/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2000 Aug 25;289(5483):1346-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Boston Biomedical Research Institute, 64 Grove Street, Watertown, MA 02472, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10958780" target="_blank"〉PubMed〈/a〉

Description: Macrophage colony-stimulating factor (M-CSF) triggers the development of cells of the monocyte-macrophage lineage and has a variety of stimulatory effects on mature cells of this class. The biologically active form of M-CSF is a disulfide-linked dimer that activates an intrinsic tyrosine kinase activity on the M-CSF receptor by inducing dimerization of the receptor molecules. The structure of a recombinant human M-CSF dimer, determined at 2.5 angstroms by x-ray crystallography, contains two bundles of four alpha helices laid end-to-end, with an interchain disulfide bond. Individual monomers of M-CSF show a close structural similarity to the cytokines granulocyte-macrophage colony-stimulating factor and human growth hormone. Both of these cytokines are monomeric in their active form, and their specific receptors lack intrinsic tyrosine kinase activity. The similarity of these structures suggests that the receptor binding determinants for all three cytokines may be similar.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pandit, J -- Bohm, A -- Jancarik, J -- Halenbeck, R -- Koths, K -- Kim, S H -- New York, N.Y. -- Science. 1992 Nov 20;258(5086):1358-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Structural Biology Division, Lawrence Berkeley Laboratory, Berkeley, CA 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1455231" target="_blank"〉PubMed〈/a〉

Description: The structure of the DNA binding domain, determined at 1.8 angstrom resolution, contains a three-helix bundle that is capped by a four-stranded antiparallel beta sheet. This structure is a variant of the helix-turn-helix motif, typified by catabolite activator protein. In the heat shock transcription factor, the first helix of the motif (alpha 2) has an alpha-helical bulge and a proline-induced kink. The angle between the two helices of the motif (alpha 2 and alpha 3) is about 20 degrees smaller than the average for canonical helix-turn-helix proteins. Nevertheless, the relative positions of the first and third helices of the bundle (alpha 1 and alpha 3) are conserved. It is proposed here that the first helix of the three-helix bundle be considered a component of the helix-turn-helix motif.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harrison, C J -- Bohm, A A -- Nelson, H C -- GM08295/GM/NIGMS NIH HHS/ -- GM44086/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jan 14;263(5144):224-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8284672" target="_blank"〉PubMed〈/a〉

Description: Insects are the most speciose group of animals, but the phylogenetic relationships of many major lineages remain unresolved. We inferred the phylogeny of insects from 1478 protein-coding genes. Phylogenomic analyses of nucleotide and amino acid sequences, with site-specific nucleotide or domain-specific amino acid substitution models, produced statistically robust and congruent results resolving previously controversial phylogenetic relations hips. We dated the origin of insects to the Early Ordovician [~479 million years ago (Ma)], of insect flight to the Early Devonian (~406 Ma), of major extant lineages to the Mississippian (~345 Ma), and the major diversification of holometabolous insects to the Early Cretaceous. Our phylogenomic study provides a comprehensive reliable scaffold for future comparative analyses of evolutionary innovations among insects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Misof, Bernhard -- Liu, Shanlin -- Meusemann, Karen -- Peters, Ralph S -- Donath, Alexander -- Mayer, Christoph -- Frandsen, Paul B -- Ware, Jessica -- Flouri, Tomas -- Beutel, Rolf G -- Niehuis, Oliver -- Petersen, Malte -- Izquierdo-Carrasco, Fernando -- Wappler, Torsten -- Rust, Jes -- Aberer, Andre J -- Aspock, Ulrike -- Aspock, Horst -- Bartel, Daniela -- Blanke, Alexander -- Berger, Simon -- Bohm, Alexander -- Buckley, Thomas R -- Calcott, Brett -- Chen, Junqing -- Friedrich, Frank -- Fukui, Makiko -- Fujita, Mari -- Greve, Carola -- Grobe, Peter -- Gu, Shengchang -- Huang, Ying -- Jermiin, Lars S -- Kawahara, Akito Y -- Krogmann, Lars -- Kubiak, Martin -- Lanfear, Robert -- Letsch, Harald -- Li, Yiyuan -- Li, Zhenyu -- Li, Jiguang -- Lu, Haorong -- Machida, Ryuichiro -- Mashimo, Yuta -- Kapli, Pashalia -- McKenna, Duane D -- Meng, Guanliang -- Nakagaki, Yasutaka -- Navarrete-Heredia, Jose Luis -- Ott, Michael -- Ou, Yanxiang -- Pass, Gunther -- Podsiadlowski, Lars -- Pohl, Hans -- von Reumont, Bjorn M -- Schutte, Kai -- Sekiya, Kaoru -- Shimizu, Shota -- Slipinski, Adam -- Stamatakis, Alexandros -- Song, Wenhui -- Su, Xu -- Szucsich, Nikolaus U -- Tan, Meihua -- Tan, Xuemei -- Tang, Min -- Tang, Jingbo -- Timelthaler, Gerald -- Tomizuka, Shigekazu -- Trautwein, Michelle -- Tong, Xiaoli -- Uchifune, Toshiki -- Walzl, Manfred G -- Wiegmann, Brian M -- Wilbrandt, Jeanne -- Wipfler, Benjamin -- Wong, Thomas K F -- Wu, Qiong -- Wu, Gengxiong -- Xie, Yinlong -- Yang, Shenzhou -- Yang, Qing -- Yeates, David K -- Yoshizawa, Kazunori -- Zhang, Qing -- Zhang, Rui -- Zhang, Wenwei -- Zhang, Yunhui -- Zhao, Jing -- Zhou, Chengran -- Zhou, Lili -- Ziesmann, Tanja -- Zou, Shijie -- Li, Yingrui -- Xu, Xun -- Zhang, Yong -- Yang, Huanming -- Wang, Jian -- Wang, Jun -- Kjer, Karl M -- Zhou, Xin -- New York, N.Y. -- Science. 2014 Nov 7;346(6210):763-7. doi: 10.1126/science.1257570.
