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. Predicted to act upstream of or within regulation of inner ear auditory receptor cell differentiation. Predicted to be located in chromosome and nucleoplasm. Orthologous to human MYCL (MYCL proto-oncogene, bHLH transcription factor). [provided by Alliance of Genome Resources, Apr 2022]
