    Summary
    Enables axon guidance receptor activity. Involved in generation of neurons and regulation of sensory neuron axon guidance. Located in plasma membrane. Is expressed in several structures, including QR.a; QR.p; muscle cell; neuroblasts; and neurons. Human ortholog(s) of this gene implicated in congenital nystagmus (multiple); hematologic cancer (multiple); panhypopituitarism; and vesicoureteral reflux. Orthologous to human ROBO1 (roundabout guidance receptor 1); ROBO2 (roundabout guidance receptor 2); and ROBO3 (roundabout guidance receptor 3). [provided by Alliance of Genome Resources, Dec 2024]
