Background
Osteopontin (OPN), also called secreted phosphoprotein 1 (SPP1), is encoded by the gene SPP1. OPN is a glycoprotein and presents different post-translational modifications according to the tissue of expression. OPN is a multifunctional phosphorylated protein involved in physiological and pathological events. Under physiological conditions, circulating and tissue OPN expression levels are relatively low, and OPN is suggested to play a key role in regulating biomineralization, wound healing, and developmental processes. Under pathological conditions, OPN is often significantly upregulated and exerts pleiotropic effects in several inflammatory, autoimmune, degenerative, fibrosis, and oncologic diseases, such as diabetes, stroke, kidney injury, cardiac fibrosis, and cancers.
