Enables netrin receptor activity and protein tyrosine kinase binding activity. Involved in several processes, including axon guidance; regulation of neuron projection development; and sex differentiation. Acts upstream of or within distal tip cell migration. Located in axonal growth cone. Expressed in several structures, including distal tip cell; excretory canal; head neurons; motor neurons; and somatic nervous system. Is an ortholog of human UNC5A (unc-5
netrin receptor A); UNC5B (unc-5
netrin receptor B); and UNC5C (unc-5
netrin receptor C).
