FUNCTION: SwissProt: Q05655 # This is calcium-independent, 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 play a role in antigen-dependent control of B-cell function.
SIZE: 676 amino acids; 77477 Da
SUBUNIT: Interacts with PDK1 (By similarity). Interacts with RAD9A and CDCP1.
SUBCELLULAR LOCATION: Cytoplasm (By similarity). Membrane; Peripheral membrane protein (By similarity).
DOMAIN: SwissProt: Q05655 The C1 domain, containing the phorbol ester/DAG-type region 1 (C1A) and 2 (C1B), is the diacylglycerol sensor. & The C2 domain is a non-calcium binding domain. It binds proteins containing phosphotyrosine in a sequence-specific manner.
PTM: Phosphorylated on Thr-507, within the activation loop. Autophosphorylated and/or phosphorylated. Although the Thr-507 phosphorylation occurs it is not a prerequisite for enzymatic activity (By similarity).
SIMILARITY: 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.
