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

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.
