Background: Osteopontin, OPN （designated Nephropontin or Secreted phosphoprotein 1, SPP-1 ）. 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. Extensively phosphorylated on serine residues.

Belongs to the osteopontin family.
