Promoter sequences are usually the sequence immediately upstream the transcription start site (TSS) or first exon. If we know the TSS of a gene, we will know with confidence where the promoter is even without experimental characterization.
WebFeb 6, 2014 · There are lots of origins of replication out there so, for simplicity’s sake, we've ignored those used in eukaryotic cells and viruses and focused only on those found in bacteria. Some common ones you might see include ColE1, pMB1 (which comes in a few slightly different but well known derivatives), pSC101, R6K, and 15A. WebFind experimentally identified DNA regulatory regions, transcription factor binding sites and regulatory variants using this open-source, open-access database and literature curation system for community-based annotation. P-Match -- transcription factor binding site search by combining patterns and weight matrices.
Promoters are genomic regions where the transcription machinery binds to initiate the transcription of specific genes. Computational tools for identifying bacterial promoters have been around for decades. However, most of these tools were designed to recognize promoters in one or few bacterial species. See more We obtained a large amount of promoter sequences from published global TSS maps (listed in Table 10). On both the training and the validation data, we had bacterial species belonging to distinct phyla and having a … See more We designed our first two assessments to demonstrate that Promotech was able to make predictions for a whole bacterial genome. Five models … See more To select Promotech’s classification model, we built two and ten models using random forest (RF) [23, 24] and recurrent neural networks (RNN) [25] (Fig. 1), respectively.
