Human Follistatin-like 1 / FSTL1 Protein, His Tag

Human Follistatin-like 1, His Tag (FS1-H5227) is expressed from human 293 cells (HEK293). It contains AA Glu 21 - Ile 308 (Accession # AAH00055).

Follistatin-related protein 1 (FSTL1) is also known as Follistatin-like protein 1 (FRP). FSTL1 is a secreted protein that contains two EF-hand domains, one follistatin-like domain, one Kazal-like domain and one VWFC domain. FSTL1 is overexpressed in synovial tissues from rheumatoid arthritis. Follistatin-like protein 1 / FSTL1 may modulate the action of some growth factors on cell proliferation and differentiation. FSTL1 binds heparin.

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 33.8 kDa. The protein migrates as 40-55 kDa under reducing (R) condition (SDS-PAGE) due to different glycosylation.
