FUNCTION: SwissProt: Q16566 # Calcium/calmodulin-dependent protein kinase belonging to a proposed calcium-triggered signaling cascade. May be involved in transcriptional regulation. May be involved in regulation of microtubule dynamics. In vitro, phosphorylates CREB1, CREBBP, PRM2, MEF2A, MEF2D and STMN1/OP18. May be involved in spermatogenesis. May play a role in the consolidation/retention of hippocampus-dependent long-term memory (By similarity).
SIZE: 473 amino acids; 51926 Da
SUBUNIT: Monomer (By similarity). Interacts with serine/threonine protein phosphatase 2A catalytic subunit, PPP2CA or PPP2CB. The interaction with PP2CA or PP2CB is mutually exclusive with binding to Ca(2+)/calmodulin.
SUBCELLULAR LOCATION: Cytoplasm (By similarity). Nucleus (By similarity). Note=Substantial localization in certain neuronal nuclei. In spermatids associated with chromatin and nuclear matrix (By similarity).
TISSUE SPECIFICITY: Expressed in epithelial ovarian cancer tissue.
PTM: Autophosphorylated and phosphorylated by CAMKK1 and CAMKK2 (By similarity). Dephosphorylated by serine/threonine protein phosphatase 2A, probably on Thr-200.
SIMILARITY: SwissProt: Q16566 ## Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. CaMK subfamily. & Contains 1 protein kinase domain.
