inhibin


inhibin
Polypeptide hormone secreted by the hypophysis, that selectively suppresses the secretion of pituitary FSH (follicle-stimulating hormone). The molecule has two subunits (14 and 18 kD), and is a product of the gene family that includes TGF b. There are two forms, ab A and ab f573 sf B, the b subunit being shared with activin. Inhibin is now, on the basis of gene knockout experiments, considered to be a tumour-suppressor, the key gene being that for inhibin- a.
