Tau-protein kinase

In enzymology, a tau-protein kinase (EC 2.7.11.26) is an enzyme that catalyzes the chemical reaction In enzymology, a tau-protein kinase (EC 2.7.11.26) is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are ATP and tau protein, whereas its two products are ADP and O-phospho-tau-protein. This enzyme belongs to the family of transferases, specifically those transferring a phosphate group to the sidechain oxygen atom of serine or threonine residues in proteins (protein-serine/threonine kinases). This enzyme participates in 14 metabolic pathways: erbb signaling pathway, cell cycle, wnt signaling pathway, hedgehog signaling pathway, axon guidance, focal adhesion, b cell receptor signaling pathway, insulin signaling pathway, melanogenesis, alzheimer's disease, colorectal cancer, endometrial cancer, prostate cancer, and basal cell carcinoma. The systematic name of this enzyme class is ATP: O-phosphotransferase. Other names in common use include ATP:tau-protein O-hosphotransferase, brain protein kinase PK40erk, cdk5/p20, CDK5/p23, glycogen synthase kinase-3beta, GSK, protein tau kinase, STK31, tau kinase, kinase, tau-protein kinase I, tau-protein kinase II, tau-tubulin kinase, TPK, TPK I, TPK II, and TTK. As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes 2JDO, 2JDR, and 2UW9.
