About Follistatin-344
- What it is
- Follistatin-344 is the longer follistatin form encoded by the full-length FST transcript, which after processing yields the mature circulating protein. It is a secreted glycoprotein that binds and neutralizes transforming growth factor beta proteins, including activin and myostatin. Because myostatin restrains muscle growth, a virus carrying the follistatin-344 sequence was tested in an early human gene therapy trial for muscle disease. It has not been approved for any use.
- How it works
- It binds activin and myostatin, blocking their access to activin type II receptors and relieving suppression of muscle growth.
- Researched for
- Muscle growth research; myostatin inhibition; activin neutralization; muscular dystrophy research
- Half-life
- Not established in humans
- Familiarity
- Advanced
- Research evidence
- Human trials - early or small
- Regulatory status
- Phase 1
- Key risk
- No serious risk is documented in the small human gene therapy trial, though broad interference with growth factor signaling remains a theoretical concern.
