A regulatory calcium-calmodulin-dependent protein kinase that specifically phosphorylates CALCIUM-CALMODULIN-DEPENDENT PROTEIN KINASE TYPE 1; CALCIUM-CALMODULIN-DEPENDENT PROTEIN KINASE TYPE 2; CALCIUM-CALMODULIN-DEPENDENT PROTEIN KINASE TYPE 4; and PROTEIN KINASE B. It is a monomeric enzyme that is encoded by at least two different genes.
