Background
Follistatin-Related Protein 1 (FSTL1) is a secreted protein that contains two EF-hand domains; one follistatin-like domain; one Kazal-like domain; and one VWFC domain. Its functional significance in physiological and pathological processes is not completely understood. However; FSTL1 is thought to modulate the action of some growth factors on cell proliferation and differentiation. FSTL1 maybe an autoantigen associated with rheumatoid arthritis.
