Protein kinase C - Wikipedia
In cell biology, protein kinase C, commonly abbreviated to PKC (EC 2.7.11.13), is a family of protein kinase enzymes that are involved in controlling the function of other proteins through the phosphorylation of hydroxyl groups of serine and threonine amino acid residues on these proteins, or a member of this family.
第二节 蛋白激酶C的信号传导通路和作用 - KKME
PKC信号通道是一条重要的细胞内信息传递通道,它存在于多种细胞内,通过催化蛋白质磷酸化反应、影响受体的上下调节、细胞膜和骨架的重塑及对转录的正负调节来调整细胞内某些特定的过程,而将各种有关的细胞膜外的生物信息在细胞膜内传递下去,从而对细胞的增殖、分化、凋亡、转录、致癌性、细胞毒效应以及细胞迁移等多种生理活动产生调控作用。 许多细胞可以表达多种PKC的亚型,而每一种亚型又可以引起细胞产生不同的作用。 对所有的PKC来说,通过细胞 …
