Involved in negative regulation of canonical Wnt signaling pathway; negative regulation of neuron projection development; and nervous system development. Acts upstream of or within negative regulation of axon extension and negative regulation of neuron apoptotic process. Located in extracellular region. Is expressed in several structures, including central nervous system; dorsal root ganglion; future brain; neural retina; and vibrissa. Orthologous to human DRAXIN (dorsal inhibitory axon guidance protein). [provided by Alliance of Genome Resources, Apr 2022]
