GDF-8 is synthesized as a 376-amino acid prepropeptide, proteolytically processed to generate a latent prodomain-mature domain complex; activation requires further cleavage by tolloid-like proteases to release the biologically active mature dimer. The mature GDF-8 signals primarily through the activin type II receptor (ActRIIB), recruiting ALK4\/ALK5 to activate Smad2\/3 transcription factors, thereby suppressing myoblast proliferation, satellite cell activation, and muscle protein synthesis.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eIn 2004, a landmark case report described a human child with a homozygous myostatin mutation exhibiting gross muscle hypertrophy from infancy, providing direct proof-of-concept for therapeutic targeting in humans.
