Mammalian protein found in Homo sapiens
Glycoprotein hormones, alpha polypeptide is a protein that in humans is encoded by the "CGA" gene.
The gonadotropin hormones, human chorionic gonadotropin (hCG), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and thyroid-stimulating hormone (TSH) are heterodimers consisting of alpha and beta subunits (also called chains) that are associated non-covalently. The alpha subunits of these four human glycoprotein hormones are identical; however, their beta chains are unique and confer biological specificity. The protein encoded by this gene is the alpha subunit and belongs to the glycoprotein hormones alpha chain family. CGA levels are regulated by ELAVL1/HuR, and the small molecule Eltrombopag, which targets HuR/RNA interactions, has been shown to reduce CGA levels in human cultured cells.
