Summary: Contributes to DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in carbon catabolite activation of transcription from RNA polymerase II promoter and regulation of cellular respiration. Part of CCAAT-binding activity factor complex. Orthologous to human NFYB (nuclear transcription factor Y subunit beta). [provided by Alliance of Genome Resources, Dec 2024]
