CD4 5是一种蛋白酪氨酸磷酸酶 ,它可以通过其蛋白酪氨酸磷酸活性使蛋白酪氨酸激酶抑制位点去磷酸化从而激活激酶 ,在淋巴细胞的活化中发挥重要作用。本文就CD4 5在淋巴细胞活化中的作用作一简单综述。
CD4 5 is a protein tyrosine phosphatase that activates kinases through dephosphorylation of protein tyrosine kinase inhibitory sites by its protein tyrosine phosphorylate activity and plays an important role in lymphocyte activation. This article briefly reviews the role of CD4 5 in lymphocyte activation.
