Mutational analysis of BTAF1–TBP interaction: BTAF1 can rescue DNA-binding defective TBP mutants
The BTAF1 transcription factor interacts with TATA-binding protein (TBP) to form the B-TFIID complex, which is involved in RNA polymerase II transcription. Here, we present an extensive mapping study of TBP residues involved in BTAF1 interaction. This shows that residues in the concave, DNA-binding surface of TBP are important for BTAF1 binding. In addition, BTAF1 interacts with residues in hel...
متن کاملNC2alpha interacts with BTAF1 and stimulates its ATP-dependent association with TATA-binding protein.
Transcriptional activity of the TATA-binding protein (TBP) is controlled by a variety of proteins. The BTAF1 protein (formerly known as TAF(II)170/TAF-172 and the human ortholog of Saccharomyces cerevisiae Mot1p) and the NC2 complex composed of NC2alpha (DRAP1) and NC2beta (Dr1) are able to bind to TBP directly and regulate RNA polymerase II transcription both positively and negatively. Here, w...
متن کاملTBP mutants defective in activated transcription in vivo.
The TATA box binding protein (TBP) plays a central and essential role in transcription initiation. At TATA box-containing genes transcribed by RNA polymerase II, TBP binds to the promoter and initiates the assembly of a multiprotein preinitiation complex. Several studies have suggested that binding of TBP to the TATA box is an important regulatory step in transcription initiation in vitro. To d...
متن کاملTranscription factor IIA derepresses TATA-binding protein (TBP)-associated factor inhibition of TBP-DNA binding.
The interaction of the general transcription factor (TF) IIA with TFIID is required for transcription activation in vitro. TFIID consists of the TATA-binding protein (TBP) and TBP associated factors (TAFIIs). TFIIA binds directly to TBP and stabilizes its interaction with TATA-containing DNA. In this work, we present evidence that TAFIIs inhibit TBP-DNA and TBP-TFIIA binding, and that TFIIA sti...
متن کاملChromatin interaction of TATA-binding protein is dynamically regulated in human cells.
Gene transcription in mammalian cells is a dynamic process involving regulated assembly of transcription complexes on chromatin in which the TATA-binding protein (TBP) plays a central role. Here, we investigate the dynamic behaviour of TBP by a combination of fluorescence recovery after photobleaching (FRAP) and biochemical assays using human cell lines of different origin. The majority of nucl...
