Enables netrin receptor binding activity and protein tyrosine kinase binding activity. Involved in generation of neurons; negative regulation of cell adhesion; and netrin-activated signaling pathway. Acts upstream of or within dendrite morphogenesis; locomotory behavior; and post-embryonic retina morphogenesis in camera-type eye. Located in several cellular components, including dendrite; growth cone; and neuronal cell body. Is expressed in several structures, including central nervous system; peripheral nervous system; sensory organ; skin; and testis. Orthologous to human DSCAM (DS cell adhesion molecule).
