Predicted to enable fibroblast growth factor receptor binding activity and growth factor activity. Acts upstream of or within several processes, including animal organ morphogenesis; cellular response to leukemia inhibitory factor; and positive regulation of macromolecule metabolic process. Predicted to be located in extracellular region. Predicted to be active in cytoplasm and extracellular space. Is expressed in several structures, including branchial pouch; cerebellum; embryo mesenchyme; surface ectoderm; and tooth. Orthologous to human FGF4 (fibroblast growth factor 4).
