protein kinase C-alpha (PKC-III, PRKCA, PKCA PRKACA)

Function

• Ca+2-activated, phospholipid-dependent serine/threonine kinase
• may play a role in cell motility by phosphorylating CSPG4
• activated by diacylglycerol
• phosphorylates a range of cellular proteins
• interacts with CENTA1, CSPG4 & PRKCABP
• binds to SDPR in the presence of phosphatidylserine

Cofactor:

• binds 3 Ca+2 per subunit
• Ca+2 bound to the C2 domain (putative)

Structure

• 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 Zn+2 fingers
• contains 1 protein kinase domain

More general terms

• protein kinase C type-A
• zinc finger protein
