PSG5, also known as pregnancy-specific beta-1-glycoprotein 5, a member of the PSG family that is mainly produced by the placental syncytiotrophoblasts during pregnancy. The function of PSG5 stimulates secretion of TH2-type cytokines from monocytes, and they may also modulate the maternal immune system during pregnancy, thereby protecting the semi-allotypic fetus from rejection. Source: Recombinant protein corresponding to aa35-335 from human PSG5, fused to His-Tag at C-terminal, expressed in insect cell.
