Summaries for CGB8 Gene

Entrez Gene Summary for CGB8 Gene

  • This gene is a member of the glycoprotein hormone beta chain family and encodes the beta 8 subunit of chorionic gonadotropin (CG). Glycoprotein hormones are heterodimers consisting of a common alpha subunit and an unique beta subunit which confers biological specificity. CG is produced by the trophoblastic cells of the placenta and stimulates the ovaries to synthesize the steroids that are essential for the maintenance of pregnancy. The beta subunit of CG is encoded by 6 genes which are arranged in tandem and inverted pairs on chromosome 19q13.3 and contiguous with the luteinizing hormone beta subunit gene.

GeneCards Summary for CGB8 Gene

CGB8 (Chorionic Gonadotropin, Beta Polypeptide 8) is a Protein Coding gene. Diseases associated with CGB8 include cryptococcosis. Among its related pathways are Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein and Peptide hormone metabolism. An important paralog of this gene is TSHB.
