在转录起始位点(the start site of transcription)上游,有一段保守启动子序列(consensus promoter sequence)。RNA polymerase 识别并且结合到特异性的启动子上(recognizes and binds specific promoter),打开(melt)转录起始位点附近的DNA双链,启动RNA的从头合成(initiate de novo synthesis of RNA)。RNA polymerase 利用NT...
The promoter region for the human GLS gene was analysed to position −5,000 bp relative to the transcription start site (TSS), and a number of putative c-Jun binding sites (<15% dissimilarity to the consensus sequence) were identified using the PROMO42 resource (Supplementary Fig. 6)....
in a DNase hypersensitive region, has higher quality, higher conservation level, and is more proximal to a transcription start site (Fig.3b). The Bayes algorithm is converged and calculates the probability that a motif is bound. Fig. 3 AccessTF, a Bayesian network model to identify TF binding...
Each transcription factor binds preferentially to a consensus sequence, or motif, usually located just upstream of the transcription start site—in other words, the promoter region. If a polymorphism disrupts that motif, the transcription factor may be less able to bind to the promoter and ...
We found that this consensus sequence was present within 49 and 34% ChIP-seq sites in quiescent and serum-stimulated cells, respectively (supplemental Tables S1 and S2). As shown in Fig. 1A, the hnRNPK ChIP signal was enriched around the transcription start site (TSS) regions. To establish...

In computational methods, position weight matrices (PWMs) are commonly applied for transcription factor binding site (TFBS) prediction. Although these matrices are more accurate than simple consensus sequences to predict actual binding sites, they usually produce a large number of false positive (FP)...
In vivo and in vitro studies showed that CcpA repressed phoPR transcription by binding directly to the cre consensus sequence present in the promoter. Primer extension and in vitro transcription studies revealed that the CcpA regulation of phoPR transcription was due to repression of P(A6), a ...
Non-template to template expression difference is shown as a function of distance from the transcription start site (TSS). b, Expression of PPARA, FOXA1 and REST TFBSs in the template and non-template orientation as a function of distance from TSS, for n = 2 background sequences. ...
These interactions are of great importance for the recognition of a consensus sequence of the −35/−10 elements by the group IV σ factors. The σI (SigI) factor is a unique σ70 that is widespread in Bacilli and Clostridia20,21,22,23,24. It contains a σ2-domain for recognition ...
