Background:

Synonyms: FS, activin-binding protein, FSH-suppressing protein (FSP)

Background: Follistatin is an autocrine acting protein that is expressed by many tissues, but at noteably higher levels in the ovary and skin. Follistatin functions to negatively regulate the signaling of a wide variety of TGF-beta family members (activin, BMPs, myostatin, GDF-11 and TGF-beta 1). Mechanistically, follistatin works as an antagonist by complexing with TGF-beta family members to prevent them from interacting with their signaling receptors. Recombinant mouse follistatin is a non-glycosylated protein, containing 289 amino acids, with a molecular weight of 31.6 kDa.
