Summary: Enables netrin receptor activity and protein domain specific binding activity. Involved in several processes, including nematode male tail tip morphogenesis; nervous system development; and regulation of neuron projection development. Acts upstream of or within dendrite morphogenesis and distal tip cell migration. Located in axonal growth cone and cell projection membrane. Part of receptor complex. Is expressed in several structures, including hermaphrodite somatic gonadal cell; motor neurons; neuroblasts; somatic nervous system; and touch receptor neurons. Human ortholog(s) of this gene implicated in colorectal cancer; congenital mirror movement disorder; and esophagus squamous cell carcinoma. Orthologous to human DCC (DCC netrin 1 receptor) and NEO1 (neogenin 1). [provided by Alliance of Genome Resources, Dec 2024]
