Protein Kinase C beta2 (PKCb2)

Protein kinase C ('PKC', EC 2.7.11.13) is a cyclic nucleotide-independent enzyme that phosphorylates serine and threonine residues in many target proteins. The PKC family has been divided into three groups differing in the enzymes' cofactor requirements: conventional (c)PKC isoforms (comprising α, βI (also known as β1), βII (also known as β2) and γ), that require diacylglycerol (DAG), Ca2+, and phospholipid for activation; novel (n)PKC isoforms (comprising δ, ε, η (also known as PKC-L), θ and µ (the mouse homolog of human PKCµ, also known as PKD)) that require DAG but not Ca2+; and atypical (a)PKC...
