Calmodulin-dependent protein kinases; Calmodulin-dependent kinases

The Ca2+/calmodulin-dependent kinase (CaMK) family has been recognized as a key mediator in living organisms and various biological processes.

CaMK II is a multifunctional cytoplasmic calcium and calmodulin-dependent protein kinase that phosphorylates and alters the function of a variety of substrates. The CaMK II pathway has been found to regulate the RANKL-induced osteoclast formation via the cAMP-response element binding protein (CREB) pathway.

Among many signaling pathways of proliferation, intracellular calciumol/L has been extensively demonstrated to be very important. In cytoplasm, calciumol/L binds to calmodulin, and then activates the CaMKs which are a family of structurally related serine/threonine protein kinases including CaMKI-IV. CaMKII, a multi functional protein kinase, is ubiquitously involved in many physiological processes including control of cell cycle, apoptosis, gene expression, and neurotransmission.
