Receptor which, together with svh-4, is involved in axon guidance to establish the tracts for the ventral and dorsal nerve cords during nervous system development (PubMed:23147028). May play a role in axon regeneration following injury in D-type motor neurons (PubMed:27984580). Expressed in neurons in head and tail, some motoneurons in ventral nerve cord, in PVP interneurons, pharynx and stomato-intestinal muscle. Expression begins during bean stage in hypodermal cells. At the 2-fold stage, also expressed in a few head and tail neurons. The protein kinase domain is predicted to be catalytically inactive. Viable. No effect on axon regeneration 24 hours following injury of D-type motor neurons. Double knockout with svh-4 results in a more enhanced axon regeneration defect of D-type motor neurons as compared to the svh-4 single mutant. Belongs to the protein kinase superfamily. Tyr protein kinase family. Insulin receptor subfamily.
