Osteopontin is a glycoprotein that was first identified in osteoblasts and is involved in bone remodeling, immune functions in fibroblasts, macrophages, and lymphocytes during inflammation and wound healing. SPP1 binds tightly to hydroxyapatite. SPP1 forms an integral part of the mineralized matrix. SPP1 is vital to cell-matrix interaction. Secreted Phosphoprotein-1 protects against cardiac ischemia-reperfusion injury via late preconditioning. Expression of both Ostepontin and CD44 in hepatocellular carcinoma is linked with advanced tumor stage and contributes to prognosis information. SPP1 is the most over-expressed gene in intrahepatic cholangiocarcinoma. Secreted Phosphoprotein-1 overexpression is related with interstitial lung diseases.
Secreted Phosphoprotein-1 Human Recombinant produced in E.Coli is single, a non-glycosylated, Polypeptide chain containing 321 amino acids fragment (17-314) and having a total molecular mass of 36.2 kDa(molecular weight on SDS-PAGE will shift up). The SPP1 protein is fused to a 20 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques.
| UniProt Protein Function: | osteopontin: Binds tightly to hydroxyapatite. Appears to form an integral part of the mineralized matrix. Probably important to cell-matrix interaction. Belongs to the osteopontin family. 5 isoforms of the human protein are produced by alternative splicing. |
| UniProt Protein Details: | Protein type:Secreted, signal peptide; Secreted Chromosomal Location of Human Ortholog: 4q22.1 Cellular Component: extracellular space; cell projection; apical part of cell; perinuclear region of cytoplasm; extracellular region Molecular Function:protein binding; extracellular matrix binding; cytokine activity Biological Process: osteoblast differentiation; extracellular matrix disassembly; neutrophil chemotaxis; extracellular matrix organization and biogenesis; response to vitamin D; biomineral formation; response to steroid hormone stimulus; negative regulation of collateral sprouting of intact axon in response to injury; positive regulation of bone resorption; decidualization; cell adhesion; inflammatory response; embryo implantation |
| NCBI Summary: | The protein encoded by this gene is involved in the attachment of osteoclasts to the mineralized bone matrix. The encoded protein is secreted and binds hydroxyapatite with high affinity. The osteoclast vitronectin receptor is found in the cell membrane and may be involved in the binding to this protein. This protein is also a cytokine that upregulates expression of interferon-gamma and interleukin-12. Several transcript variants encoding different isoforms have been found for this gene.
