SOST Human Recombinant produced in E. Coli is a single, non-glycosylated, polypeptide chain (a.a 24-213) containing 200 amino acids including a 10 a.a N-terminal His tag. The total molecular mass is 22.8kDa (calculated). Sclerostin (SOST) is a secreted glycoprotein with a C-terminal cysteine knot-like (CTCK) domain and sequence similarity to the DAN (differential screening-selected gene aberrative in neuroblastoma) family of bone morphogenetic protein (BMP) antagonists. Sclerostin functions as a negative regulator of bone growth, by inhibiting bone formation. SOST is widely expressed at low levels, with highest levels in the bone, cartilage, kidney, liver, bone marrow and primary osteoblasts differentiated for 21 days. SOST gene defects cause sclerosteosis and bone dysplasia.
