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.
