Protein kinase A (PKA) is the cAMP dependent protein kinase. It can transmit the exocellular signal, phosphorylate the membrane protein and regulate the proliferation, differentiation and apoptosis of cell.

• 蛋白激酶A(Protein Kinase A, PKA)为依赖cAMP(环腺苷酸,cyclic adenosine monomphsopate)的蛋白激酶,有传递胞外的刺激信号,影响膜蛋白的磷酸化而改变细胞膜的通透性,调控细胞的增殖、分化和凋亡等作用。
