Pregnancy Specific Beta-1-Glycoprotein 8 (PSG8)
PSG8 gene contains 6 exons.The human pregnancy-specific glycoproteins (PSGs) are a group of molecules that are mainly produced by the placental syncytiotrophoblasts during pregnancy. PSGs comprise a subgroup of the carcinoembryonic antigen (CEA) family, which belongs to the immunoglobulin superfamily.Studies by several groups resulted in the mapping of the CEA gene family to 19q13.1-q13.2.The PSG subgroup is located telomeric of the CEA subgroup, and together they span approximately 1.1 to 1.2 Mb .Using a high-resolution restriction fragment fingerprinting technique, Olsen et al. (1994) assembled 256 cosmids spanning the PSG region on 19q13.2 into a single 700-kb contig. FISH to sperm pronuclei and cosmid walking experiments indicated that this PSG contig is telomeric of CGM8 at the telomeric end of the CEA subgroup gene cluster.
