84-3435-28　SPARC, CT (Osteonectin, Secreted Protein Acidic and Rich in Cysteine) 100ug　303641

特徴

• SPARC, secreted protein acidic and rich in cysteine, also known as Osteonectin, is a protein that in humans is encoded by the SPARC gene.
• The human SPARC gene is 26.5kb long, and contains 10 exons and 9 introns and is located on chromosome 5q31-q33.
• SPARC is a glycoprotein of 40kD.
• SPARC is an acidic, cysteine-rich glycoprotein consisting of a single polypeptide chain that can be broken into 4 domains: 1) an Ca++ binding domains near the glutamic acidic-rich region at the amino terminus (domain I), 2) a cysteine-rich (domain II), 3) a hydrophilic region (domain III) and 4) an EF hand motif at the carboxy terminus region (domain IV).
• Osteonectin is a glycoprotein in the bone that binds sodium.
• It is secreted by osteoblasts during bone formation, initiating mineralization and promoting mineral crystal formation.
• Osteonectin also shows affinity for collagen in addition to bone mineral calcium.
• A correlation between osteonectin over expression and ampullary cancers and chronic pancreatitis has been found.
