Predicted to enable growth factor activity; type 1 fibroblast growth factor receptor binding activity; and type 2 fibroblast growth factor receptor binding activity. Involved in anterior/posterior pattern specification; mesoderm development; and nervous system development. Acts upstream of or within negative regulation of endodermal cell fate specification. Predicted to be located in extracellular region. Predicted to be active in cytoplasm and extracellular space. Is expressed in several structures, including blastomere; cardiovascular system; forebrain; paraxial mesoderm; and sensory system. Human ortholog(s) of this gene implicated in hypogonadotropic hypogonadism 20 with or without anosmia. Orthologous to human FGF17 (fibroblast growth factor 17).
