Summary: Enables DNA-binding transcription repressor activity, RNA polymerase II-specific and cis-regulatory region sequence-specific DNA binding activity. Involved in negative regulation of G1/S transition of mitotic cell cycle by negative regulation of transcription from RNA polymerase II promoter and positive regulation of pseudohyphal growth by positive regulation of transcription from RNA polymerase II promoter. Located in cellular bud and nucleus. Part of Rpd3L complex. [provided by Alliance of Genome Resources, Apr 2022]
