Function

Calcium/calmodulin-dependent protein kinase belonging to a proposed calcium-triggered signaling cascade involved in a number of cellular processes. Isoform 1, isoform 2 and isoform 3 phosphorylate CAMK1 and CAMK4. Isoform 3 phosphorylates CAMK1D. Isoform 4, isoform 5 and isoform 6 lacking part of the calmodulin- binding domain are inactive. 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 (By similarity). Seems to be involved in hippocampal activation of CREB1 (By similarity). May play a role in neurite growth. Isoform 3 may promote neurite elongation, while isoform 1 may promoter neurite branching. {ECO:0000250, ECO:0000269PubMed:11395482, ECO:0000269PubMed:12935886, ECO:0000269PubMed:21957496, ECO:0000269PubMed:9662074}.

Subcellular Localization

Nucleus {ECO:0000250}. Cytoplasm {ECO:0000269PubMed:21957496}. Cell projection {ECO:0000269PubMed:21957496}. Note=Predominantly nuclear in unstimulated cells (By similarity). Found in the cytoplasm and neurites after forskolin induction. {ECO:0000250}.

Disease Associations

Tissue Specificity

Ubiquitously expressed with higher levels in the brain. Intermediate levels are detected in spleen, prostate, thyroid and leukocytes. The lowest level is in lung. {ECO:0000269PubMed:9662074}.
