Predicted to enable cell-cell adhesion mediator activity; netrin receptor binding activity; and protein tyrosine kinase binding activity. Involved in positive regulation of axon extension involved in axon guidance. Predicted to be located in several cellular components, including dendrite; growth cone; and neuronal cell body. Predicted to be active in axon and plasma membrane. Orthologous to human DSCAM (DS cell adhesion molecule). [provided by Alliance of Genome Resources, Apr 2022]
