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，可被鈣和第二信使二酰甘油激活。pkc家族成員磷酸化多種蛋白質靶點，已知參與多種細胞信號傳導途徑。PKC家族成員也作為一類腫瘤啟動子佛波酯的主要受體。pkc家族的每一個成員都有一個特定的表達譜，并且被認為在細胞中起著獨特的作用。該基因編碼的蛋白質是pkc家族成員之一。據報道，這種蛋白激酶參與多種不同的細胞功能，如B細胞活化、凋亡誘導、內皮細胞增殖和腸道糖吸收。對小鼠的研究也表明，這種激酶還可能調節神經元功能，并與壓力后恐懼誘導的沖突行為相關。另外還報道了編碼不同亞型的剪接轉錄變體。
Protein kinase C (PKC) is a family of serine- and threonine-specific protein kinases that can be activated by calcium and 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 protein kinase has been reported to be involved in many different cellular functions, such as B cell activation, apoptosis induction, endothelial cell proliferation, and intestinal sugar absorption. Studies in mice also suggest that this kinase may also regulate neuronal functions and correlate fear-induced conflict behavior after stress. Alternatively spliced transcript variants encoding distinct isoforms have been reported.
