蛋白激酶C（PKC）是一個絲氨酸和蘇氨酸特異性蛋白激酶家族，可被鈣和第二信使甘油二酯激活pkc家族成員磷酸化多種蛋白質靶點，參與多種細胞信號傳導途徑。PKC家族成員也是一類腫瘤促進劑佛波酯的主要受體pkc家族的每個成員都有一個特定的表達譜，并被認為在細胞中發揮著獨特的作用。該基因編碼的蛋白是pkc家族成員之一。據報道，這種激酶在許多不同的細胞過程中發揮作用，如細胞粘附、細胞轉化、細胞周期檢查點和細胞體積控制。小鼠的基因敲除研究表明，這種激酶可能是心肌細胞收縮力和鈣離子處理的基本調節因子。
Protein kinase C (PKC) is a family of serine- and threonine-specific protein kinases that can be activated by calcium and the second messenger diacylglycerol. PKC family members phosphorylate a wide variety of protein targets and are known to be involved in diverse cellular signaling pathways. PKC family members also serve as major receptors for phorbol esters, a class of tumor promoters. Each member of the PKC family has a specific expression profile and is believed to play a distinct role in cells. The protein encoded by this gene is one of the PKC family members. This kinase has been reported to play roles in many different cellular processes, such as cell adhesion, cell transformation, cell cycle checkpoint, and cell volume control. Knockout studies in mice suggest that this kinase may be a fundamental regulator of cardiac contractility and Ca(2+) handling in myocytes.
