Follistatin (FST) is a secreted glycoprotein that was first identified as a follicleA-stimulating hormone inhibiting substance in ovarian follicular fluid (1 2). Human Follistatin cDNA encodes a 344 amino acid (aa) protein with a 29 aa signal sequence an NA-terminal atypical TGF binding domain three Follistatin domains that contain EGFA-like and kazalA-like motifs and a highly acidic CA-terminal tail. Follistatin is a secreted protein that binds to ligands of the TGF-Beta family and regulates their activity by inhibiting their access to signaling receptors. It was originally discovered as activin antagonists whose activity suppresses expression and secretion of the pituitary hormone FSH (follicle stimulating hormone).
