Follistatin 344 | Muscle Growth & Myostatin

Follistatin 344 is a research protein studied for how it regulates signals involved in muscle growth, recovery, and tissue development. It is especially known for research involving myostatin, a protein that normally helps limit muscle growth, although follistatin interacts with several biological signals rather than myostatin alone.

In scientific terms, Follistatin 344 is a 344-amino-acid precursor form of follistatin that binds members of the TGF-beta superfamily, including activins and myostatin. Research examines its role in skeletal muscle biology, tissue regeneration, reproductive biology, and cellular signaling. It should be distinguished from processed follistatin isoforms and engineered follistatin-based compounds.
