Predicted to enable extracellular matrix binding activity and heparin binding activity. Predicted to be involved in several processes, including extracellular matrix organization; limb development; and regulation of osteoblast differentiation. Predicted to act upstream of or within positive regulation of cell-substrate adhesion. Predicted to be active in basement membrane and extracellular space. Human ortholog(s) of this gene implicated in microphthalmia with limb anomalies. Orthologous to human SMOC1 (SPARC related modular calcium binding 1).
