Predicted to enable growth factor activity; type 1 fibroblast growth factor receptor binding activity; and type 2 fibroblast growth factor receptor binding activity. Acts upstream of or within fibroblast growth factor receptor signaling pathway and positive regulation of cell population proliferation. Predicted to be located in extracellular region. Predicted to be active in cytoplasm and extracellular space. Is expressed in several structures, including arterial system; central nervous system; embryo ectoderm; embryo mesenchyme; and skeleton. Human ortholog(s) of this gene implicated in hypogonadotropic hypogonadism 20 with or without anosmia. Orthologous to human FGF17 (fibroblast growth factor 17).
