Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in male sex differentiation and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including adult walking behavior; transmission of nerve impulse; and ventral spinal cord interneuron specification. Predicted to be active in nucleus. Orthologous to human DMRT3 (doublesex and mab-3 related transcription factor 3). [provided by Alliance of Genome Resources, Apr 2022]
