Predicted to enable fibroblast growth factor receptor binding activity and growth factor activity. Acts upstream of or within several processes, including inner ear morphogenesis; post-anal tail morphogenesis; and thymus development. Located in Golgi apparatus. Is expressed in several structures, including brain; branchial arch; egg cylinder; jaw; and sensory organ. Orthologous to human FGF3 (fibroblast growth factor 3).
