SPP1 - secreted phosphoprotein 1 Gene
Also Known as OPN; BNSP; BSPI; ETA-1
Species: Homo sapiens
About SPP1
This gene has 26 transcripts (splice variants), 120 orthologues and is associated with 2 phenotypes. Biased expression in placenta (RPKM 1043.5), gall bladder (RPKM 1025.4) and 3 other tissues.
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.
