IUBMB Enzyme Nomenclature


Accepted name: Ca2+/calmodulin-dependent protein kinase

Reaction: ATP + a protein = ADP + a phosphoprotein

Other name(s): ATP:caldesmon O-phosphotransferase; caldesmon kinase; caldesmon kinase (phosphorylating); Ca2+/calmodulin-dependent microtubule-associated protein 2 kinase; Ca2+/calmodulin-dependent protein kinase 1; Ca2+/calmodulin-dependent protein kinase II; Ca2+/calmodulin-dependent protein kinase IV; Ca2+/calmodulin-dependent protein kinase kinase; Ca2+/calmodulin-dependent protein kinase kinase β; calmodulin-dependent kinase II; CaM kinase; CaM kinase II; CAM PKII; CaM-regulated serine/threonine kinase; CaMKI; CaMKII; CaMKIV; CaMKKα; CaMKKβ; microtubule-associated protein 2 kinase; STK20

Systematic name: ATP:protein phosphotransferase (Ca2+/calmodulin-dependent)

Comments: Requires calmodulin and Ca2+ for activity. A wide range of proteins can act as acceptor, including vimentin, synapsin, glycogen synthase, myosin light chains and the microtubule-associated tau protein. Not identical with EC (myosin-light-chain kinase) or EC (tau-protein kinase).
