    Beschreibung: Sequence preferences of DNA binding proteins are a primary mechanism by which cells interpret the genome. Despite the central importance of these proteins in physiology, development, and evolution, comprehensive DNA binding specificities have been determined experimentally for only a few proteins. Here, we used microarrays containing all 10-base pair sequences to examine the binding specificities of 104 distinct mouse DNA binding proteins representing 22 structural classes. Our results reveal a complex landscape of binding, with virtually every protein analyzed possessing unique preferences. Roughly half of the proteins each recognized multiple distinctly different sequence motifs, challenging our molecular understanding of how proteins interact with their DNA binding sites. This complexity in DNA recognition may be important in gene regulation and in the evolution of transcriptional regulatory networks.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2905877/" 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/PMC2905877/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Badis, Gwenael -- Berger, Michael F -- Philippakis, Anthony A -- Talukder, Shaheynoor -- Gehrke, Andrew R -- Jaeger, Savina A -- Chan, Esther T -- Metzler, Genita -- Vedenko, Anastasia -- Chen, Xiaoyu -- Kuznetsov, Hanna -- Wang, Chi-Fong -- Coburn, David -- Newburger, Daniel E -- Morris, Quaid -- Hughes, Timothy R -- Bulyk, Martha L -- R01 HG003985/HG/NHGRI NIH HHS/ -- R01 HG003985-01/HG/NHGRI NIH HHS/ -- R01 HG003985-02/HG/NHGRI NIH HHS/ -- R01 HG003985-03/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2009 Jun 26;324(5935):1720-3. doi: 10.1126/science.1162327.

    Beschreibung: The extensive somatic diversification of immune receptors is a hallmark of higher vertebrates. However, whether molecular diversity contributes to immune protection in invertebrates is unknown. We present evidence that Drosophila immune-competent cells have the potential to express more than 18,000 isoforms of the immunoglobulin (Ig)-superfamily receptor Down syndrome cell adhesion molecule (Dscam). Secreted protein isoforms of Dscam were detected in the hemolymph, and hemocyte-specific loss of Dscam impaired the efficiency of phagocytic uptake of bacteria, possibly due to reduced bacterial binding. Importantly, the molecular diversity of Dscam transcripts generated through a mechanism of alternative splicing is highly conserved across major insect orders, suggesting an unsuspected molecular complexity of the innate immune system of insects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watson, Fiona L -- Puttmann-Holgado, Roland -- Thomas, Franziska -- Lamar, David L -- Hughes, Michael -- Kondo, Masahiro -- Rebel, Vivienne I -- Schmucker, Dietmar -- 1RO1-NS46747-01/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2005 Sep 16;309(5742):1874-8.

    Beschreibung: The giant sarcomeric protein titin contains a protein kinase domain (TK) ideally positioned to sense mechanical load. We identified a signaling complex where TK interacts with the zinc-finger protein nbr1 through a mechanically inducible conformation. Nbr1 targets the ubiquitin-associated p62/SQSTM1 to sarcomeres, and p62 in turn interacts with MuRF2, a muscle-specific RING-B-box E3 ligase and ligand of the transactivation domain of the serum response transcription factor (SRF). Nuclear translocation of MuRF2 was induced by mechanical inactivity and caused reduction of nuclear SRF and repression of transcription. A human mutation in the titin protein kinase domain causes hereditary muscle disease by disrupting this pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lange, Stephan -- Xiang, Fengqing -- Yakovenko, Andrey -- Vihola, Anna -- Hackman, Peter -- Rostkova, Elena -- Kristensen, Jakob -- Brandmeier, Birgit -- Franzen, Gereon -- Hedberg, Birgitta -- Gunnarsson, Lars Gunnar -- Hughes, Simon M -- Marchand, Sylvie -- Sejersen, Thomas -- Richard, Isabelle -- Edstrom, Lars -- Ehler, Elisabeth -- Udd, Bjarne -- Gautel, Mathias -- G0200496(63216)/Medical Research Council/United Kingdom -- G0300213/Medical Research Council/United Kingdom -- PG/03/049/15364/British Heart Foundation/United Kingdom -- New York, N.Y. -- Science. 2005 Jun 10;308(5728):1599-603.

    Beschreibung: The essential Cdc13 protein in the yeast Saccharomyces cerevisiae is a single-stranded telomeric DNA binding protein required for chromosome end protection and telomere replication. Here we report the solution structure of the Cdc13 DNA binding domain in complex with telomeric DNA. The structure reveals the use of a single OB (oligonucleotide/oligosaccharide binding) fold augmented by an unusually large loop for DNA recognition. This OB fold is structurally similar to OB folds found in the ciliated protozoan telomere end-binding protein, although no sequence similarity is apparent between them. The common usage of an OB fold for telomeric DNA interaction demonstrates conservation of end-protection mechanisms among eukaryotes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mitton-Fry, Rachel M -- Anderson, Emily M -- Hughes, Timothy R -- Lundblad, Victoria -- Wuttke, Deborah S -- GM55867/GM/NIGMS NIH HHS/ -- GM59414/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2002 Apr 5;296(5565):145-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, University of Colorado, Boulder, CO 80309, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11935027" target="_blank"〉PubMed〈/a〉

    Beschreibung: Posttranslational modifications play key roles in regulating chromatin plasticity. Although various chromatin-remodeling enzymes have been described that respond to specific histone modifications, little is known about the role of poly[adenosine 5'-diphosphate (ADP)-ribose] in chromatin remodeling. Here, we identify a chromatin-remodeling enzyme, ALC1 (Amplified in Liver Cancer 1, also known as CHD1L), that interacts with poly(ADP-ribose) and catalyzes PARP1-stimulated nucleosome sliding. Our results define ALC1 as a DNA damage-response protein whose role in this process is sustained by its association with known DNA repair factors and its rapid poly(ADP-ribose)-dependent recruitment to DNA damage sites. Furthermore, we show that depletion or overexpression of ALC1 results in sensitivity to DNA-damaging agents. Collectively, these results provide new insights into the mechanisms by which poly(ADP-ribose) regulates DNA repair.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3443743/" 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/PMC3443743/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ahel, Dragana -- Horejsi, Zuzana -- Wiechens, Nicola -- Polo, Sophie E -- Garcia-Wilson, Elisa -- Ahel, Ivan -- Flynn, Helen -- Skehel, Mark -- West, Stephen C -- Jackson, Stephen P -- Owen-Hughes, Tom -- Boulton, Simon J -- 064414/Wellcome Trust/United Kingdom -- 11224/Cancer Research UK/United Kingdom -- A3549/Cancer Research UK/United Kingdom -- A5290/Cancer Research UK/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Cancer Research UK/United Kingdom -- Department of Health/United Kingdom -- New York, N.Y. -- Science. 2009 Sep 4;325(5945):1240-3. doi: 10.1126/science.1177321.
