Usuage: is fascinating protein that can increase muscle mass beyond natural potential by suppressing myostatin. Scientists first identified  while examining porcine (re: pig) follicular fluid in the ovaries.

Description:
 
 is a secreted glycoprotein that was first identified as a follicle­stimulating hormone inhibiting substance in ovarian follicular fluid.Human  cDNA encodes a 344 amino acid protein with a 29 aa signal sequence, an N­terminal atypical TGF binding domain, three  domains that contain EGF ­like and kazal­like motifs, and a highly acidic C­terminal tail.  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. In addition to being a natural antagonist,  can inhibit the activity of other TGF-Beta ligands including BMP-2,-4,-6,-7, Myostatin, GDF-11, and TGF-Beta1.  is expressed in the pituitary, ovaries, decidual cells of the endometrium, and in some other tissues. Recombinant human 315 is a 34.7 kDa protein containing amino acids 30-344 of the FST-344 protein.

also known as activin-binding protein is a protein that in humans is encoded by the FST gene. is an autocrine glycoprotein that is expressed in nearly all tissues of higher animals.Its primary function is the binding and bioneutralization of members of the TGF-β superfamily, with a particular focus on activin, a paracrine hormone.

 

315 (FST 315 ) Function: 

Binds directly to activin and functions as an activin antagonist. Specific inhibitor of the biosynthesis and secretion of pituitary follicle stimulating hormone (FSH).
