Glycoprotein hormone receptors (version 2019.4) in the IUPHAR/BPS Guide to Pharmacology Database
Glycoprotein hormone receptors (provisional nomenclature ) are activated by a non-covalent heterodimeric glycoprotein made up of a common α chain (glycoprotein hormone common alpha subunit CGA, P01215), with a unique β chain that confers the biological specificity to FSH, LH, hCG or TSH. There is binding cross-reactivity across the endogenous agonists for each of the glycoprotein hormone receptors. The deglycosylated hormones appear to exhibit reduced efficacy at these receptors .
