/calmodulin-dependent protein kinase II (CaM kinase II or CaMKII) is a serine/threonine-specific protein kinase that is regulated by the /calmodulin complex. CaMKII is involved in many signaling cascades and is thought to be an important mediator of learning and memory. CaMKII is also necessary for homeostasis and reuptake in cardiomyocytes, chloride transport in epithelia, positive T-cell selection, and CD8 T-cell activation. Misregulation of CaMKII is linked to Alzheimer’s disease, Angelman syndrome, and heart arrhythmia. ==Types== There are two types of CaM kinase: * Specialized CaM kinases, such as the myosin light chain kinase that phosphorylates myosin, causing smooth muscles to contract * Multifunctional CaM kinases, also collectively called ''CaM kinase II'', which play a role in neurotransmitter secretion, transcription factor regulation, and glycogen metabolism. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ca2+/calmodulin-dependent protein kinase II」の詳細全文を読む スポンサード リンク
