Transcription: why are TAFs essential?
The TAFs are transcription factors associated with the TATA-binding protein, and until recently they were assumed to link specific activators to the general transcription machinery. Recent results suggest that the essential functions of TAFs are not as coactivators of transcription but as determinants of promoter selectivity.
