Abstract
Phosphatidic acid can replace phosphatidylserine in the activation of protein kinase C. However, in the presence of diolein, the addition of Ca2+ results in the inhibition of the enzyme. This phenomenon could lead to a negative feedback regulation of protein kinase C activity as a result of stimulation of the cycling of phosphatidylinositol.
摘要
磷脂酸在蛋白激酶C的激活过程中可取代磷脂酰丝氨酸。然而，在二油精存在的情况下，添加Ca2+会导致该酶受到抑制。由于磷脂酰肌醇循环的刺激，这种现象可能导致蛋白激酶C活性的负反馈调节。
