Is an ortholog of human BHLHE23 (basic helix-loop-helix family member e23
). Is predicted to have protein dimerization activity. Is involved in positive regulation of dopaminergic synaptic transmission and positive regulation of transcription by RNA polymerase II. Is expressed in CEPshDL; CEPshDR; CEPshVL; CEPshVR; and ventral cord neurons. Human ortholog(s) of this gene are implicated in congenital malabsorptive diarrhea 4 and persistent hyperplastic primary vitreous.
