Enables calcium ion binding activity and extracellular matrix binding activity. Acts upstream of or within several processes, including bone development; cellular response to growth factor stimulus; and pigmentation. Located in extracellular matrix and extracellular space. Is expressed in several structures, including alimentary system; extraembryonic component; genitourinary system; nervous system; and sensory organ. 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).
