Description
Calcium/calmodulin-dependent protein kinase belonging to a proposed calcium-triggered signaling cascade involved in a number of cellular processes. Phosphorylates CAMK1 and CAMK4. Phosphorylates CAMK1D (By similarity). Seems to be involved in hippocampal activation of CREB1 (By similarity). Efficiently phosphorylates 5'-AMP-activated protein kinase (AMPK) trimer, including that consisting of PRKAA1, PRKAB1 and PRKAG1. This phosphorylation is stimulated in response to Ca(2+) signals. May play a role in neurite growth. Isoform 2 may promote neurite elongation, while isoform 1 may promoter neurite branching
