Common Transactivation Motif 9aaTAD recruits multiple general co-activatorsTAF9, MED15, CBP and p300

Abstract

More than 2000 transcription factors are involved in the human gene regulation to provide cellular function and development. Transactivation domain, TAD, mediates the interaction of transcription factors with general transcriptional co-activators such as TAF9, MED15, CBP and p300. Recently reported NMR-data for interactions of these co-activators with transcription factors reveal tightly binding of KIX and TAZ domains to common 9aaTAD motif. Nine-amino-acid Trans-Activation Domain, 9aaTAD, defines a transactivation domain common to a large super-family of eukaryotic transcription factors represented in yeast by Gal4, Oaf1, Pdr1, Rtg3, Pho4, Gln3, Gcn4 and in mammals by p53, E2A, NFAT, NFkB, HSF1, NF-IL6, MLL, EBNA2, VP16. The 9aaTAD family was derived from the transcription factor Oaf1 and its close orthologs Gal4, Pdr1, Leu3, Tea1 and Cha4.
