Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and WD40-repeat domain binding activity. Involved in several processes, including cellular response to retinoic acid; positive regulation of cell population proliferation; and positive regulation of collagen biosynthetic process. Predicted to be located in cytosol and nucleoplasm. Biomarker of transient cerebral ischemia. Orthologous to human MYB (MYB proto-oncogene, transcription factor).
