| Specificity: |
This kit recognizes Human OPN in samples. No significant cross-reactivity or interference between Human OPN and analogues was observed. |
| Sample Type: |
Serum, plasma and other biological fluids |
| Post Translational Modifications | Forms covalent cross-links mediated by transglutaminase TGM2, between a glutamine and the epsilon-amino group of a lysine residue, forming homopolymers and heteropolymers, increasing its collagen binding properties. Extensively phosphorylated by FAM20C in the extracellular medium at multiple sites within the S-x-E/pS motif. The phosphorylated form inhibits hydroxyapatite crystallization. Dephosphorylation via a mechanism involving ALPL/TNAP promotes hydroxyapatite crystallization. O-glycosylated. Isoform 5 is GalNAc O-glycosylated at Thr-59 or Ser-62. |
| Function | Major non-collagenous bone protein that binds tightly to hydroxyapatite. Appears to form an integral part of the mineralized matrix. Probably important to cell-matrix interaction. Acts as a cytokine involved in enhancing production of interferon-gamma and interleukin-12 and reducing production of interleukin-10 and is essential in the pathway that leads to type I immunity. |
