phospholamban

Abstract: Phospholamban (PLB) is a prominent regulator of myocardial contractility and a reversible inhibitor of the cardiac sarcoplasmic reticulum Ca2+ ATPase activity.

受蛋白（phospholamban）是心收缩的一个重要调节因子，可抑制心钙ATPase的活性、降低其对钙的亲和力。

In normal cardiac muscles, phospholamban can be phosphorylated at distinct sites by various protein kinases and release its inhibition to sarcoplasmic reticulum Ca2+ ATPase.

正情况下，受蛋白可被不同的蛋白酸化从而解除其钙ATPase的抑制作用。
