Recombinant Human Pregnancy-specific beta-1-glycoprotein 4 (PSG4) Fragment (aa 35-419) - A high-purity protein fragment encompassing the complete Ig-like domain architecture, ideal for functional studies of pregnancy-specific glycoprotein domains in reproductive biology research.

Pregnancy-specific beta-1-glycoprotein 4 (PSG4) is a secreted protein belonging to the pregnancy-specific glycoprotein family, which are abundantly expressed during pregnancy and play important roles in maternal-fetal interactions. As a secreted protein, PSG4 functions in the extracellular space, suggesting potential roles in cell signaling, immune modulation, or other intercellular communication processes critical for successful pregnancy maintenance. The secreted nature indicates this protein may act as a circulating factor or local signaling molecule at the maternal-fetal interface.
