show Brenda entry

EC number

2.7.11.17

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)

CAS registry number

141467-21-2

Comment

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 2.7.11.18 (myosin-light-chain kinase) or EC 2.7.11.26 (tau-protein kinase).

History

created 1989 as EC 2.7.1.123, transferred 2005 to EC 2.7.11.17 (EC 2.7.1.120 incorporated 2005)
