Predicted to enable fibronectin binding activity; identical protein binding activity; and insulin-like growth factor binding activity. Predicted to be involved in cell migration; positive regulation of stress-activated MAPK cascade; and regulation of insulin-like growth factor receptor signaling pathway. Located in collagen-containing extracellular matrix and extracellular space. Is expressed in several structures, including blastocyst; compacted morula; genitourinary system; liver; and spleen. Human ortholog(s) of this gene implicated in obesity. Orthologous to human IGFBP6 (insulin like growth factor binding protein 6). [provided by Alliance of Genome Resources, Apr 2022]
