Literature
Research context
Follistatin-344 is the longer secreted isoform of the FST gene product, comprising a heparin-binding N-terminal domain and three cysteine-rich follistatin domains. The literature centres on its neutralisation of activin A and GDF-8 (myostatin) in the TGF-β superfamily, and on gene-transfer studies in murine skeletal muscle. Molecular mass varies with expression system and glycosylation, so no single value is quoted here.
