phospholamban

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

受磷蛋白（phospholamban）是心肌收缩的一个重要调节因子，心肌肌浆网钙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，受磷蛋白被不同的蛋白激酶磷酸化除其肌浆网钙ATPase的作用。
