Predicted to enable DNA-binding transcription factor activity and E-box binding activity. Involved in positive regulation of dopaminergic synaptic transmission and positive regulation of transcription by RNA polymerase II. Predicted to be located in nucleus. Expressed in CEPshDL; CEPshDR; CEPshVL; CEPshVR; and ventral cord neurons. Is an ortholog of human BHLHE22 (basic helix-loop-helix family member
e22) and BHLHE23 (basic helix-loop-helix family member
e23).
