PKC ζ (phospho Thr560) Rabbit Polyclonal Antibody

Protein kinase C (PKC) zeta is a member of the PKC family of serine/threonine kinases which are involved in a variety of cellular processes such as proliferation, differentiation and secretion. Unlike the classical PKC isoenzymes which are calcium-dependent, PKC zeta exhibits a kinase activity which is independent of calcium and diacylglycerol but not of phosphatidylserine. Furthermore, it is insensitive to typical PKC inhibitors and cannot be activated by phorbol ester. Unlike the classical PKC isoenzymes, it has only a single zinc finger module. These structural and biochemical properties indicate that the zeta subspecies is related to, but distinct from other isoenzymes of PKC. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008], catalytic activity:ATP + a protein = ADP + a phosphoprotein., domain:The C1 domain does not bind the diacylglycerol (DAG) ., domain:The OPR domain mediates mutually exclusive interactions with SQSTM1 and PARD6B., enzyme regulation:Phosphatidylinositol 3,4,5-trisphosphate might be a physiological activator. Two specific sites, Thr-410 (activation loop of the kinase domain) and Thr-560 (turn motif), need to be phosphorylated for its full activation., function:PKC is activated by diacylglycerol which in turn phosphorylates a range of cellular proteins. PKC also serves as the receptor for phorbol esters, a class of tumor promoters. Subunit of a quaternary complex that plays a central role in epithelial cell polarization., function:This is a calcium-independent, phospholipid-dependent, serine- and threonine-specific enzyme., similarity:Belongs to the protein kinase superfamily., similarity:Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. PKC subfamily., similarity:Contains 1 AGC-kinase C-terminal domain., similarity:Contains 1 OPR domain., similarity:Contains 1 phorbol-ester/DAG-type zinc finger., similarity:Contains 1 protein kinase domain., subcellular location:In the retina, localizes in the terminals of the rod bipolar cells (By similarity) .
