General annotation (Comments)
| Function | This is a calcium-activated, phospholipid-dependent, serine- and threonine-specific enzyme. 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. May be considered as a novel component of the NF-kappa-B signaling axis responsible for the survival and activation of B-cells after BCR cross-linking. |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Cofactor | Binds 3 calcium ions per subunit. The ions are bound to the C2 domain By similarity. |
| Subunit structure | Interacts with PDK1 By similarity. |
| Subcellular location | CytoplasmBy similarity. Membrane; Peripheral membrane proteinBy similarity. |
| Post-translational modification | Phosphorylation on Thr-500 within the activation loop renders it competent to autophosphorylate. Subsequent autophosphorylation of Thr-641 maintains catalytic competence, and autophosphorylation on Ser-660 appears to release the kinase into the cytosol. Autophosphorylation on other sites i.e. in the N-terminal and hinge regions have no effect on enzyme activity By similarity. |
| Sequence similarities | Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. PKC subfamily. Contains 1 AGC-kinase C-terminal domain. Contains 1 C2 domain. Contains 2 phorbol-ester/DAG-type zinc fingers. Contains 1 protein kinase domain. |
