Enables chemoattractant activity. Involved in positive regulation of transcription, DNA-templated and radial glial cell differentiation. Acts upstream of or within several processes, including animal organ development; positive regulation of cell population proliferation; and regulation of signal transduction. Located in extracellular space. Is expressed in several structures, including alimentary system; central nervous system; embryo mesenchyme; genitourinary system; and sensory organ. Used to study LADD syndrome and intestinal atresia. Human ortholog(s) of this gene implicated in LADD syndrome and aplasia of lacrimal and salivary glands. Orthologous to human FGF10 (fibroblast growth factor 10). [provided by Alliance of Genome Resources, Apr 2022]
