The TATA binding protein-associated factor 5 (TAF5) is a subunit of TFIID and SAGA complexes involved in RNA polymerase II transcription initiation and histone acetylation. Although members of the putative SAGA complex in Arabidopsis such as GCN5 and ADA2b have important roles in plant development...
The Arabidopsis mutant stg1 identifies a function for TBP-associated factor 10 in plant osmotic stress adaptation. Gao,X,Ren,F,Lu,YT.The Arabidopsis mutant stg1 identifies a function for TBP-associated factor 10 in plant osmotic stress adaptation. Plant and Cell ... Xiang,Gao,Feng,... - ...
However, how transcription initiation complex integrates light signals from enhancer-bound transcription factors remains unknown. In this work, we characterized mutations within the Arabidopsis HAF2 gene encoding TATA-binding protein-associated factor TAF1 (or TAFII250). The mutation of HAF2 induced ...
Interestingly, in several cases suppression of different TATA box mutants by altered TBPs was gene or RNA polymerase specific suggesting that assembly of TBP into specific complexes containing different TBP-associated factors may alter DNA binding specificity of the protein.D J...
Both the general factor TFIID (refs 2,3), including the constituent TBP (TATA-binding polypeptide) and associated factors, and the interacting factor TFIIB (refs 9-11) have been implicated as targets for various activators. Towards an understanding of the basis for activator function, including ...
