Predicted to be an extracellular matrix structural constituent. Involved in chemorepulsion of axon and regulation of synapse assembly. Acts upstream of or within several processes, including animal organ morphogenesis; generation of neurons; and nuclear migration. Located in basement membrane and cytoplasm. Is expressed in several structures, including alimentary system; central nervous system; integumental system; lung; and sensory organ. Human ortholog(s) of this gene implicated in congenital mirror movement disorder. Orthologous to human NTN1 (netrin 1). [provided by Alliance of Genome Resources, Apr 2022]
