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 regulation of transcription by RNA polymerase II. Human ortholog(s) of this gene implicated in hypogonadotropic hypogonadism. Orthologous to human NHLH2 (nescient helix-loop-helix 2).
