osteopontin

Bone-specific sialoprotein (57 kD: probably two similar peptides) that links cells and the hydroxyapatite of mineralised matrix; has RGD sequence. Found only in calcified bone, probably produced by osteoblasts.

Osteopontin

Osteopontin (OPN), also known as bone sialoprotein I (BSP-1 or BNSP), early T-lymphocyte activation (ETA-1), secreted phosphoprotein 1 (SPP1), 2ar and Rickettsia resistance (Ric), is a protein that in humans is encoded by the SPP1 gene (secreted phosphoprotein 1). The murine ortholog is Spp1. Osteopontin is a SIBLING (glycoprotein) that was first ...

Osteopontin

- an adhesive glycoprotein related to sialoproteins, which is secreted by osteoclasts to assist in their adhesion to the bone surface. After bone resorption it may then act as a signal to stimulate osteoblast activity

osteopontin

Type: Term Pronunciation: os′tē-ō-pon′tin Definitions: 1. A secreted phosphoprotein, produced by many epithelial cell types, which is highly negatively charged and frequently associated with mineralization processes. It is found in plasma, urine, milk, and bile. Transformed cells express osteopontin in elevated levels. Synonym...
