Recombinant full length human OPN protein with molecular weight 35 kDa.
Product Specifications
Background
Osteopontin (OPN), also known as bone sialoprotein I (BSP-1 or BNSP), secreted phosphoprotein 1 (SPP1), is a human gene product. The gene has 7 exons, spans 5 kilobases in length and in humans it is located on 4q13. The protein is composed of ~300 amino acids residues and has ~30 carbohydrate residues attached including 10 sialic acid residues, which are attached to the protein during post-translational modification in the Golgi apparatus. Osteopontin has been implicated as an important factor in bone remodeling. Specifically, research suggests it plays a role in anchoring osteoclasts to the mineral matrix of bones.
