Ett utbrett protein som binder direkt till aktiviner. Det verkar som aktivinantagonist, hämmar utsöndring av follikelstimulerande hormon (FSH), reglerar celldifferentiering och spelar en viktig roll vid embryobildningen. Follistatin består av en enkel, glykosylerad polypeptidkedja på ca 37 kD och ingår inte i inhibingruppen (inhibiner). Proteinet binder även och neutraliserar många medlemmar i TGF-betafamiljen.
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.
