MeSH definition : A broadly distributed protein that binds directly to ACTIVINS. It functions as an
activin antagonist, inhibits FOLLICLE STIMULATING HORMONE secretion, regulates CELL
DIFFERENTIATION, and plays an important role in embryogenesis. Follistatin is a single
glycosylated polypeptide chain of approximately 37-kDa and is not a member of the
inhibin family (INHIBINS). Follistatin also binds and neutralizes many members of
the TRANSFORMING GROWTH FACTOR BETA family.;
