Predicted to enable integrin binding activity. Acts upstream of or within bone mineralization; cellular response to growth factor stimulus; and extracellular matrix organization. Predicted to be located in extracellular space and vesicle. Is expressed in several structures, including axial skeleton; bone; facial prominence; jaw; and limb. Orthologous to human IBSP (integrin binding sialoprotein). [provided by Alliance of Genome Resources, Apr 2022]
