Predicted to enable extracellular matrix binding activity and integrin binding activity. Involved in several processes, including negative regulation of collateral sprouting of intact axon in response to injury; osteoblast differentiation; and positive regulation of bone resorption. Located in several cellular components, including extracellular space; perinuclear region of cytoplasm; and vesicle. Used to study several diseases, including encephalomyelitis; myocarditis; radiculopathy; renovascular hypertension; and visual epilepsy. Biomarker of autosomal dominant polycystic kidney disease; calcinosis; and glomerulosclerosis. Human ortholog(s) of this gene implicated in several diseases, including autoimmune disease (multiple); biliary atresia; coronary artery disease (multiple); disease of cellular proliferation (multiple); and hepatitis. Orthologous to human SPP1 (secreted phosphoprotein 1). [provided by Alliance of Genome Resources, Apr 2022]
