Follistatin-315 is a splice variant of the protein follistatin, naturally found in the body. It functions by binding to and inhibiting activins and other members of the TGF-beta superfamily, which are involved in regulating cell growth and differentiation. Early work on Follistatin-315 focused on its role in muscle growth and fertility. This peptide also has significant implications in the reproductive tissue system, particularly impacting ovarian function. Today, it is primarily studied for its effects on:
- Muscle growth regulation
- Fertility enhancement
- Ovarian function studies
- Cell differentiation processes
- Activin inhibition
Beyond that, work continues on its broader implications in cell signaling pathways.
