Predicted to enable several functions, including DNA-binding transcription factor activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and identical protein binding activity. Predicted to be involved in neuron differentiation and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within cerebral cortex regionalization; negative regulation of transcription, DNA-templated; and neuron differentiation. Predicted to be active in nucleus. Orthologous to human BHLHE22 (basic helix-loop-helix family member e22). [provided by Alliance of Genome Resources, Apr 2022]
