    Beschreibung: The probability that a residue in a protein is part of a coiled-coil structure was assessed by comparison of its flanking sequences with sequences of known coiled-coil proteins. This method was used to delineate coiled-coil domains in otherwise globular proteins, such as the leucine zipper domains in transcriptional regulators, and to predict regions of discontinuity within coiled-coil structures, such as the hinge region in myosin. More than 200 proteins that probably have coiled-coil domains were identified in GenBank, including alpha- and beta-tubulins, flagellins, G protein beta subunits, some bacterial transfer RNA synthetases, and members of the heat shock protein (Hsp70) family.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lupas, A -- Van Dyke, M -- Stock, J -- AI20980/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1991 May 24;252(5009):1162-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Princeton University, NJ 08544.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2031185" target="_blank"〉PubMed〈/a〉

    Beschreibung: In human neutrophils, as in other cell types, Ras-related guanosine triphosphate-binding proteins are directed toward their regulatory targets in membranes by a series of posttranslational modifications that include methyl esterification of a carboxyl-terminal prenylcysteine residue. In intact cells and in a reconstituted in vitro system, the amount of carboxyl methylation of Ras-related proteins increased in response to the chemoattractant N-formyl-methionyl-leucyl-phenylalanine (FMLP). Activation of Ras-related proteins by guanosine-5'-O-(3-thiotriphosphate) had a similar effect and induced translocation of p22rac2 from cytosol to plasma membrane. Inhibitors of prenylcysteine carboxyl methylation effectively blocked neutrophil responses to FMLP. These findings suggest a direct link between receptor-mediated signal transduction and the carboxyl methylation of Ras-related proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Philips, M R -- Pillinger, M H -- Staud, R -- Volker, C -- Rosenfeld, M G -- Weissmann, G -- Stock, J B -- AR-07176-18/AR/NIAMS NIH HHS/ -- GM 20277/GM/NIGMS NIH HHS/ -- GM-8309/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1993 Feb 12;259(5097):977-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, New York University Medical Center, NY 10016.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8438158" target="_blank"〉PubMed〈/a〉
