It regulates transforming growth factor-beta superfamily ligands, being described as a ligand antagonist. It consists of a N-terminal domain with a modified TB fold and three follistatin domains (FSD1-3) each of which is subdivided in EGF-like and Kazal-like subdomains [1-4]. This domain is important for ligand specificity.
