Enables RNA polymerase II-specific DNA-binding transcription factor binding activity and transcription coactivator activity. Involved in positive regulation of transcription by RNA polymerase II and regulation of cellular respiration. Part of CCAAT-binding activity factor complex.
SGD Description
Transcription factor; subunit of the heme-activated, glucose-repressed Hap2p/3p/4p/5p CCAAT-binding complex, a transcriptional activator and global regulator of respiratory gene expression; provides the principal activation function of the complex; involved in diauxic shift
