Plays a role in the regulation of neuronal activity. In AWA and AWC neurons, plays a role in regulating olfactory adaptation by controlling the forgetting sensory responses to odorants such as diacetyl and isoamyl alcohol (PubMed:28924007). May play a role in regulating daf-7 expression in ASI neurons in response to bacterial small RNAs (PubMed:32908307). In ASI neurons, promotes dauer formation in response to pheromones such as the ascarosides ascr#2 and ascr#3 (PubMed:26976437). Restricted to neuronal cell bodies, absent from dendrites and axons (PubMed:21437263). Strong expression in many neurons, very weak expression is also detected in others tissues. RNAi-mediated knockdown results in defective avoidance behavior in response to P.aeruginosa.
