钙调神经磷酸酶

CALCINEURIN

钙调神经磷酸酶是一种依赖Ca2+－CaM的磷蛋白磷酸酶。主要存在于脑组织神经元中，由催化亚基A和调节亚基B1：1组成。钙调神经磷酸酶是一个多底物的磷蛋白磷酸酶。它的活性还受到Ni2+和Mn2+等金属离子的调节。

Calcineurin. a kind of Ca2+CaM dependent protein phesphatase. chiefly existing in cerebral tissue neuron. is composed of catalytic subunit A and regutatory subunit B at the ratio of 1: 1, It possess multiple substrates. Whose activity is regulated by divalant metals such as Ni2+ and Mn2+.
