Acts as a transcriptional regulator (PubMed:27487365, PubMed:29672507). May mediate transcriptional activation by binding to the E-box motif 5'-CANNTG-3' (PubMed:29672507). Required for the correct morphology, terminal identity and function of the ADL sensory neurons by controlling the expression of the ADL-specific gene repertoire, including chemoreceptor encoding genes, ion channel encoding genes, neuropeptides and the neurotransmitter eat-4 (PubMed:29672507). Regulates the expression of the srh-234 chemoreceptor encoding gene in the ADL neurons under feeding conditions (PubMed:27487365). Plays a role in the chemorepulsive response toward ascaroside pheromones mediated by the ADL sensory neurons (PubMed:29672507). Expressed in the ADL sensory neurons. Expressed in the ADL precursor cells in the precomma stage embryo (PubMed:29672507). Expressed during embryogenesis, larval stages and in adult animals (PubMed:27487365, PubMed:29672507). RNAi-mediated knockdown in a rrf-3 RNAi hypersensitive mutant background leads to decreased expression of srh-234 in the cell body of ADL sensory neurons (PubMed:27487365).
