Enables calmodulin-dependent protein kinase activity. Predicted to be involved in peptidyl-serine phosphorylation. Predicted to act upstream of or within phosphorylation. Located in endomembrane system and plasma membrane. Part of calcium- and calmodulin-dependent protein kinase complex. Is expressed in several structures, including genitourinary system; heart; nervous system; and retina. Orthologous to human CAMK1G (calcium/calmodulin dependent protein kinase IG).
