Enables calcium ion binding activity. Involved in several processes, including animal organ development; response to L-ascorbic acid; and response to lead ion. Located in several cellular components, including extracellular space; nucleus; and vesicle. Is active in glutamatergic synapse. Biomarker of diabetic angiopathy; membranoproliferative glomerulonephritis; membranous glomerulonephritis; myocardial infarction; and stomach carcinoma. Human ortholog(s) of this gene implicated in cervix carcinoma; endometrial carcinoma; and osteogenesis imperfecta type 17. Orthologous to human SPARC (secreted protein acidic and cysteine rich).
