Folistatina 315

Folistatina, 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.

Folistatina 344 e 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).

A folistatina é uma proteína fascinante que pode aumentar a massa muscular além do potencial natural, suprimindo a miostatina. Os cientistas identificaram pela primeira vez a folistatina ao examinarem (ré: porco) fluido folicular nos ovários.

A folistatina é encontrada naturalmente no músculo esquelético de quase todos os mamíferos com características avançadas ou desenvolvidas, como os humanos, roedores, e vacas. A folistatina é rica no aminoácido não essencial cistina, mas ao contrário da maioria das proteínas discutidas no mundo do fitness, folistatina tem carboidratos ligados a ela.
