Transcription factor (By similarity). Plays a role in neuronal signaling in polymodal sensory neuron ASH, downstream of sensory receptor activation (PubMed:33665029). Required for maintenance of AVG synapses (PubMed:27144354). Dimorphically expressed in the dimorphically connected interneuron AVG; expression is observed in the AVG in males, but not in hermaphrodites. Decreased response to nose touch, but normal motor and sensory behaviors and normal levels of glutamate receptor glr-1 (PubMed:33665029). Small but significant decrease in response to high osmolarity (PubMed:33665029). Decreased reversal responses to direct stimulation of the polymodal sensory neuron ASH as compared to wild type (PubMed:33665029). Defects in male mating behavior; reduced efficiency in locating vulva of partner (PubMed:27144354). Alterations in AVG interneuron synaptic wiring in a dmd-5 mutant background (PubMed:27144354). Belongs to the DMRT family.
