NCBI and Uniprot Product Information
NCBI Description
This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer. This protein negatively regulates skeletal muscle cell proliferation and differentiation. Mutations in this gene are associated with increased skeletal muscle mass in humans and other mammals.

Uniprot Description
MSTN: Acts specifically as a negative regulator of skeletal muscle growth. Defects in MSTN are the cause of muscle hypertrophy (MSLHP). MSLHP is a condition characterized by increased muscle bulk and strength. Affected individuals are exceptionally strong. Belongs to the TGF-beta family.
