SPP1 / Osteopontin

secreted phosphoprotein 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.

Gene Name: secreted phosphoprotein 1
Synonyms: SPP1, BSPI, BNSP, Bone sialoprotein 1, ETA-1, Nephropontin, OPN, Secreted phosphoprotein 1, SPP-1, SPP1/CALPHA1 fusion, Urinary stone protein, Uropontin, Osteopontin, Bone sialoprotein I
Target Sequences: NM_000582 NP_000573.1 P10451
