Follistatin 315

Follistatin, also called activin-binding protein, is found in nearly all tissues of vertebrate animals. Its primary function is to neutralize members of the TGF-β family, which play fundamental roles in everything from growth and development to energy homeostasis and immune system regulation. In particular, follistatin interacts with activin, which plays an important part in cell proliferation and cell death as well as in the immune response as it applies to wound repair.

Follistatin 344 Ve 315 are engineered analogues of naturally occurring follistatin. Both are created by alternative splicing of the follistatin mRNA transcript. Scientific research in non-human primates as well as in mice have indicated that both molecules are capable of improving muscle growth by antagonizing myostatin (a member of the TGF-β family).

Follistatin, miyostatini baskılayarak kas kütlesini doğal potansiyelin ötesinde artırabilen büyüleyici bir proteindir.. Bilim insanları follistatini ilk kez domuz etini incelerken tespit etti (tekrar: domuz) yumurtalıklarda foliküler sıvı.

Follistatin, gelişmiş veya gelişmiş özelliklere sahip hemen hemen tüm memelilerin iskelet kaslarında doğal olarak bulunur., insanlar gibi, kemirgenler, ve inekler. Follistatin, esansiyel olmayan amino asit sistin açısından yüksektir ancak fitness dünyasında tartışılan çoğu proteinin aksine, Follistatin'e bağlı karbonhidratlar vardır.
