General description

Osteopontin is a single-chain polypeptide. It is highly phosphorylated sialoprotein that is a prominent component of the mineralized extracellular matrices of bones and teeth. It is characterized by the presence of a polyaspartic acid sequence and sites of Ser/Thr phosphorylation that mediate hydroxyapatite binding, and a highly conserved RGD motif that mediates cell attachment/signaling. Expression of osteopontin in a variety of tissues indicates a multiplicity of functions that involve one or more of these conserved motifs. While the lack of a clear phenotype in osteopontin "knockout" mice has not established a definitive role for osteopontin in any tissue, recent studies have provided some novel and intriguing insights into the versatility of this enigmatic protein in diverse biological events, including developmental processes, wound healing, immunological responses, tumorigenesis, bone resorption, and calcification. The ability of osteopontin to stimulate cell activity through multiple receptors linked to several interactive signaling pathways can account for much of the functional diversity.
