Abstract
The primary amino acid structures of the 43-kDa (A) and 15-kDa (B) subunits of the 58-kDa form of the hormone inhibin have been elucidated by cloning and analysis of cDNA species derived from bovine granulosa cell mRNA. The A subunit (Mr = 32,298) is a protein of 300 amino acids with two potential N-glycosylation sites and two potential proteolytic processing sites and has a pre-pro region of 60 amino acids. The mature B subunit (Mr = 12,977) is a protein of 116 amino acids synthesized from a separate mRNA. These data establish that a 31-kDa form of inhibin also isolated from bovine follicular fluid, with subunits of 20 OrkDa (A(C)) and 15 kDa (B), is derived from the 58-kDa form by proteolytic processing of the A subunit.
