Probable tyrosine-protein kinase receptor which regulates the dauer/non-dauer developmental decision probably by controlling daf-3 transcriptional activity in parallel or together with the TGF-beta pathway (PubMed:11063683, PubMed:18674914). Regulates integration of conflicting sensory cues in AIA interneurons (PubMed:21414922). May act as a receptor for hen-1 (PubMed:18674914, PubMed:21414922). In AWA neurons, together with hen-1, plays a role in regulating olfactory adaptation by controlling the forgetting sensory responses to odorants such as diacetyl (PubMed:28924007). ATP + L-tyrosyl-[protein] = ADP + H(+) + O-phospho-L-tyrosyl-[protein] Interacts (via cytoplasmic domain) with fsn-1 (via SPRY domain). Expressed in AIA sensory neurons. Belongs to the protein kinase superfamily. Tyr protein kinase family. Insulin receptor subfamily.
