251-467 4.39e-113

C-terminal domain of TATA Binding Protein (TBP) Associated Factor 6 (TAF6); This model characterizes the carboxy (C)-terminal domain of TATA Binding Protein (TBP) Associated Factor 6 (TAF6), which is one of several TAFs that bind TBP and are involved in forming the Transcription Factor IID (TFIID) complex. This C-terminal HEAT repeat domain of TAF6 (TAF6C) is proposed to form a homodimer that effectively bridges the downstream promoter-interacting TAFs (TAF1, -2, and -7) with lobe B of TFIID. This domain influences the TAF6-TAF9 complex, is thus important for TFIID assembly, and may trigger signals from transcriptional effectors. The HEAT domain motif is generally involved in protein/protein interactions, and in A. locustae, the conserved TAF6C domain is formed by five HEAT repeats, tightly packed against each other, defining a single structural domain. TFIID is one of several General Transcription Factors (GTFs), which also include TFIIA, TFIIB, TFIIE, TFIIF and TFIIH, that are involved in the accurate initiation of transcription by RNA polymerase II in eukaryotes. TFIID plays a key role in the recognition of promoter DNA and assembly of the pre-initiation complex. The TFIID complex is composed of the TBP and at least 13 TAFs. TAFs are named after their electrophoretic mobility in polyacrylamide gels in different species. A new, unified nomenclature has been suggested for the pol II TAFs to show the relationship between TAF orthologs and paralogs. Several hypotheses are proposed for TAFs' functions such as serving as activator-binding sites, core-promoter recognition, or a role in essential catalytic activity. These TAFs, with the help of specific activators, are required only for expression of a subset of genes and are not universally involved for transcription, as are GTFs. In yeast and human cells, TAFs have been found as components of other complexes besides TFIID. Several TAFs interact via histone-fold domain (HFD) motifs; the HFD is the interaction motif involved in heterodimerization of the core histones and their assembly into nucleosome octamers. The minimal HFD contains three alpha-helices linked by two loops and is found in core histones, TAFs and many other transcription factors. TFIID has a histone octamer-like substructure. TAF6 is a shared subunit of histone acetyltransferase complex SAGA and TFIID complexes. The N-terminal HFD of TAF6, interacts with the HFD of TAF9 and makes a novel histone-like heterodimer that is structurally related to histones H4 and H3. TAF6 may also interact with the downstream core promoter element (DPE).

49-114 5.45e-31

histone-fold domain found in transcription initiation factor TFIID subunit 6 (TAF6) and similar proteins; TAF6, also called TATA Binding Protein (TBP) associated factor 6, RNA polymerase II TBP-associated factor subunit E, transcription initiation factor TFIID 70 kDa subunit (TAF(II)70, TAFII-70, TAFII70), or transcription initiation factor TFIID 80 kDa subunit (TAF(II)80, TAFII-80, TAFII80), is a TBP-associated factor (TAF). TAFs are components of the transcription factor IID (TFIID) complex, PCAF histone acetylase complex, and TBP-free TAFII complex (TFTC). TIIFD is a multimeric protein complex that plays a central role in mediating promoter responses to various activators and repressors. TFIID and PCAF are composed of TATA binding protein (TBP) and several TAFs. TBP is not part of TFTC.

TATA box binding protein associated factor; TAFs (TATA box binding protein associated factors) are part of the transcription initiation factor TFIID multimeric protein complex. TFIID is composed of the TATA box binding protein (TBP) and a number of TAFs. The TAFs provide binding sites for many different transcriptional activators and co-activators that modulate transcription initiation by Pol II. TAF proteins adopt a histone-like fold.

C-terminal domain of TATA Binding Protein (TBP) Associated Factor 6 (TAF6); This model characterizes the carboxy (C)-terminal domain of TATA Binding Protein (TBP) Associated Factor 6 (TAF6), which is one of several TAFs that bind TBP and are involved in forming the Transcription Factor IID (TFIID) complex. This C-terminal HEAT repeat domain of TAF6 (TAF6C) is proposed to form a homodimer that effectively bridges the downstream promoter-interacting TAFs (TAF1, -2, and -7) with lobe B of TFIID. This domain influences the TAF6-TAF9 complex, is thus important for TFIID assembly, and may trigger signals from transcriptional effectors. The HEAT domain motif is generally involved in protein/protein interactions, and in A. locustae, the conserved TAF6C domain is formed by five HEAT repeats, tightly packed against each other, defining a single structural domain. TFIID is one of several General Transcription Factors (GTFs), which also include TFIIA, TFIIB, TFIIE, TFIIF and TFIIH, that are involved in the accurate initiation of transcription by RNA polymerase II in eukaryotes. TFIID plays a key role in the recognition of promoter DNA and assembly of the pre-initiation complex. The TFIID complex is composed of the TBP and at least 13 TAFs. TAFs are named after their electrophoretic mobility in polyacrylamide gels in different species. A new, unified nomenclature has been suggested for the pol II TAFs to show the relationship between TAF orthologs and paralogs. Several hypotheses are proposed for TAFs' functions such as serving as activator-binding sites, core-promoter recognition, or a role in essential catalytic activity. These TAFs, with the help of specific activators, are required only for expression of a subset of genes and are not universally involved for transcription, as are GTFs. In yeast and human cells, TAFs have been found as components of other complexes besides TFIID. Several TAFs interact via histone-fold domain (HFD) motifs; the HFD is the interaction motif involved in heterodimerization of the core histones and their assembly into nucleosome octamers. The minimal HFD contains three alpha-helices linked by two loops and is found in core histones, TAFs and many other transcription factors. TFIID has a histone octamer-like substructure. TAF6 is a shared subunit of histone acetyltransferase complex SAGA and TFIID complexes. The N-terminal HFD of TAF6, interacts with the HFD of TAF9 and makes a novel histone-like heterodimer that is structurally related to histones H4 and H3. TAF6 may also interact with the downstream core promoter element (DPE).

51-113 1.07e-07

histone fold domain (HFD) superfamily; The histone fold domain (HFD) is a structurally conserved interaction motif involved in heterodimerization of the core histones and their assembly into the nucleosome octamer. Histone fold heterodimers play crucial roles in gene regulation. The minimal HFD consists of three alpha helices connected by two short, unstructured loops. The HFD is found in core histones, TATA box-binding protein-associated factors (TAFs), and many other transcription factors. HFD plays a role in the nucleosomal core particle by conserving histone interactions; these contain more than one HFD. The structure of the nucleosome core particle has two modes that have the largest interaction surfaces, and these are the H3-H4 and H2A-H2B heterodimer interactions. Several TAFs interact via histone-fold (HF) motifs. Five HF-containing TAF pairs have been described in transcription factor II D (TFIID): TAF6-TAF9, TAF4-TAF12, TAF11-TAF13, TAF8-TAF10 and TAF3-TAF10.
