About Myostatin
- What it is
- GDF-8, known as myostatin, is a naturally occurring protein of the transforming growth factor beta superfamily produced mainly in skeletal muscle. It normally limits muscle growth so muscles do not become too large, acting as a negative regulator. Loss-of-function changes in animals and rare humans cause increased muscle mass. Because it restrains growth, research targets blocking it rather than administering it.
- How it works
- Myostatin signals through activin type II receptors and SMAD proteins to suppress skeletal muscle cell growth and differentiation.
- Researched for
- Muscle growth regulation; myostatin inhibition research; muscular dystrophy research; livestock genetics
- Half-life
- Not established in humans
- Familiarity
- Advanced
- Research evidence
- Animal studies only
- Regulatory status
- Phase 3
- Key risk
- None documented; this is the endogenous protein that limits muscle growth and is not administered as a therapy.
