Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and cAMP response element binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within regulation of DNA-templated transcription. Predicted to be located in nucleus. Predicted to be part of ATF4-CREB1 transcription factor complex. Is expressed in brain and telencephalon. Orthologous to human CREM (cAMP responsive element modulator).
