This family represents the N-terminus of the 31kD subunit (42kD in drosophila) of transcription initiation factor IID (TAFII31). TAFII31 binds to p53, and is an essential requirement for p53 mediated transcription activation.
The general transcription factor, TFIID, consists of the TATA-binding protein (TBP) associated with a series of TBP-associated factors (TAFs) that together participate in the assembly of the transcription preinitiation complex. The conserved region ...
The general transcription factor, TFIID, consists of the TATA-binding protein (TBP) associated with a series of TBP-associated factors (TAFs) that together participate in the assembly of the transcription preinitiation complex. The conserved region is found at the C-terminal of most member proteins. The crystal structure of hTAFII28 with hTAFII18 shows that this region is involved in the binding of these two subunits. The conserved region contains four alpha helices and three loops arranged as in histone H3 [1,2].
This family includes the Spt3 yeast transcription factors and the 18kD subunit from human transcription initiation factor IID (TFIID-18). Determination of the crystal structure reveals an atypical histone fold [1]
This is the C-terminal, Delta, part of the TAF8 protein [1]. The N-terminal is generally the histone fold domain, Bromo_TP (Pfam:PF07524). TAF8 is one of the key subunits of the transcription factor for pol II, TFIID. TAF8 is one of the several gener ...
This is the C-terminal, Delta, part of the TAF8 protein [1]. The N-terminal is generally the histone fold domain, Bromo_TP (Pfam:PF07524). TAF8 is one of the key subunits of the transcription factor for pol II, TFIID. TAF8 is one of the several general cofactors which are typically involved in gene activation to bring about the communication between gene-specific transcription factors and components of the general transcription machinery [2].
