Spp1 Gene Summary [Rat]

Predicted to enable extracellular matrix binding activity; integrin binding activity; and small molecule binding activity. Involved in several processes, including negative regulation of collateral sprouting of intact axon in response to injury; positive regulation of bone resorption; and response to macrophage colony-stimulating factor. Located in several cellular components, including extracellular space; perinuclear region of cytoplasm; and vesicle. Used to study several diseases, including encephalomyelitis; glomerulonephritis; myocarditis; radiculopathy; and renovascular hypertension. 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, Jul 2025]

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Spp1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
