Storage Instruction
If unopened the kit may be stored at 2-8°C for up to 1 month. If the kit will not be used within 1 month, store the components separately, according to the component table in the manual.
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
Additional Info
Tissue Specificity
Detected in cerebrospinal fluid and urine (at protein level). Bone. Found in plasma.
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.
