Function

UNC5_CAEEL Receptor for netrin (unc-6) required for axon guidance (PubMed:8332188, PubMed:11454756). Mediates axon repulsion of neuronal growth cones in the developing nervous system upon ligand binding (PubMed:1384987, PubMed:8332188, PubMed:11454756, PubMed:9473333). Axon migration is mediated by the secreted unc-6, which promotes attraction of neurons and axons through binding to the unc-40 receptor, while repulsion requires both unc-5 and unc-40 receptors (PubMed:11454756, PubMed:9473333). Involved in the ventral-dorsal and anterior-posterior migration of distal tip cells along the body, which may be mediated by Wnt receptor mom-5, ced-10/Rac, ced-12/ELMO and mig-2/RhoG (PubMed:10631179, PubMed:26292279, PubMed:17716643).[1] [2] [3] [4] [5] [6] [7]
