Predicted to enable signaling receptor binding activity. Involved in outflow tract septum morphogenesis. Acts upstream of or within several processes, including animal organ development; blood vessel morphogenesis; and embryonic morphogenesis. Predicted to be located in external side of plasma membrane. Predicted to be active in cytoplasm and extracellular space. Is expressed in several structures, including alimentary system; branchial arch; embryo ectoderm; embryo mesenchyme; and sensory organ. Used to study DiGeorge syndrome and tetralogy of Fallot. Human ortholog(s) of this gene implicated in hypogonadotropic hypogonadism 6 with or without anosmia and prostate carcinoma in situ. Orthologous to human FGF8 (fibroblast growth factor 8). [provided by Alliance of Genome Resources, Apr 2022]
