关于CD47/IAP: CD47 is involved in the increase in intracellular calcium concentration that occurs upon cell adhesion to extracellular matrix. The protein is also a receptor for the C-terminal cell-binding domain of thrombospondin, and it may play a role in membrane transport and signal transduction. This protein has broad tissue distribution, and is reduced in expression on Rh erythrocytes. 关键词:重组人白细胞表面抗原CD47蛋白,重组人IAP,重组白细胞表面抗原CD47,JN1819
