Predicted to enable several functions, including Hsp70 protein binding activity; S100 protein binding activity; and signaling receptor binding activity. Acts upstream of or within several processes, including organ induction; positive regulation of epithelial cell proliferation; and positive regulation of nitrogen compound metabolic process. Located in extracellular matrix and extracellular space. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in brain ischemia; cleft lip; myocardial infarction; schizophrenia; and urinary bladder cancer. Orthologous to human FGF1 (fibroblast growth factor 1).
