Enables growth factor activity. Involved in stem cell development. Acts upstream of or within several processes, including animal organ development; positive regulation of macromolecule metabolic process; and positive regulation of signal transduction. Located in extracellular space. Is expressed in several structures, including alimentary system; central nervous system; extraembryonic component; genitourinary system; and sensory organ. Human ortholog(s) of this gene implicated in several diseases, including Parkinsonism; corneal neovascularization; diabetic neuropathy; gastric ulcer; and impotence. Orthologous to human FGF2 (fibroblast growth factor 2). [provided by Alliance of Genome Resources, Apr 2022]
