These proteins represent a new family of protein kinases, related by sequence to the bacterial protein kinases but by function to the eukaryotic serine protein kinases. Arg288 is required for recognition by BCKDK of the phosphorylation site on the E1alpha subunit of the BCKDH complex. BCKDK inhibits the dehydrogenase activity of the BCKDH complex by introducing a negative charge into the active-site pocket of the E1 component. Protein starvation of rats induces an increase in the amount of BCKDK bound to the BCKDH complex. This causes inactivation of the BCKDH complex and conserves branched-chain amino acids for protein synthesis in the protein-starved state. Expression of the different PDK isoenzymes is tissue specific, and the different PDK isoenzymes are unique with respect to kinetic parameters for ATP and ADP and sensitivity to allosteric effectors (NADH, NAD+, coenzyme A, acetyl-CoA, pyruvate, and dichloroacetate). Preliminary experiments indicate that an increased amount of PDK2 protein partly explains the increase in PDK activity that occurs in rat liver in response to chemically induced diabetes.</p>","PeriodicalId":76981,"journal":{"name":"Advances in second messenger and phosphoprotein research","volume":"31 ","pages":"105-11"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20276677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In transfected model systems, G-protein-coupled receptors that couple to pertussis toxin-insensitive G proteins of the Gq/11 family mediate this activation predominantly via a PKC-dependent mechanism. In contrast, activation of MAP kinase by receptors that couple to pertussis toxin-sensitive Gi proteins is PKC-independent and requires downstream activation of the low-molecular-weight G protein, Ras. This pathway can be inhibited by coexpression of peptides that sequester Gbetagamma subunits, and is mimicked by overexpression of Gbetagamma subunits. This Ras-dependent MAP kinase activation requires tyrosine phosphorylation of \"docking proteins,\" including the shc adapter protein, and depends upon recruitment of Grb2/Sos1 complexes to the plasma membrane, thus resembling the pathway of MAP kinase activation employed by the receptor tyrosine kinases. Other molecules, including PI-3-kinases and phosphotyrosine phosphatases, probably also contribute to Gbetagamma-subunit-mediated assembly of a mitogenic signaling complex. Identification of the G-protein-coupled, receptor-regulated tyrosine kinase(s), and the means by which the mitogenic signaling complex is assembled at the plasma membrane, remain subjects of further study.</p>","PeriodicalId":76981,"journal":{"name":"Advances in second messenger and phosphoprotein research","volume":"31 ","pages":"263-77"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20276689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
