Function

[CNG_CAEEL] Required for normal thermosensation and chemosensation sensory behavior (PubMed:8893027). Required, downstream of receptor-type guanylate cyclase gcy-9, for CO2-mediated responses in BAG neurons (PubMed:21173231). Required, downstream of receptor-type guanylate cyclase gcy-14, for alkaline pH-mediated responses in ASE-left (ASEL) neurons (PubMed:23664973). Involved in the development of ASJ sensory neuron axon during late larval stages and in the maintenance of normal axon morphology in the adult. Regulates dauer formation (PubMed:9486798). In ASI and ASJ sensory neurons, controls behavioral response to P.aeruginosa by up-regulating the transcription of daf-7, a member of the TGF-beta family (PubMed:25303524). In AWB and AWC sensory neurons, mediates the recognition of food oders which subsequently allows for the detection of preferred food sources (PubMed:25009271).^[1] ^[2] ^[3] ^[4] ^[5] ^[6]
