In addition, the use of enhancers in eukaryotic transcription allows the promoter sites in remote location on the DNA to initiate transcription. Transcriptional repressors can bind to promoter or enhancer regions and block transcription. Gene expression has been commonly characterized as a measure of how much, how fast, when and where this process happens. In this paper we utilize Convolutional Neural Networks (CNN) to analyze sequence characteristics of prokaryotic and eukaryotic promoters and build their predictive models. A promoter is a regulatory region of DNA located upstream (towards the 5' region) of of a gene, providing a control point for regulated gene transcription.. They typically lie upstream of the gene and can have regulatory elements several kilobases away from the transcriptional start site. A typical promoter sequence is thought to comprise some sequence motifs positioned at specific sites relative to the TSS. The promoter contains specific DNA sequences that are recognized by proteins known as transcription factors. plants, animals- comprise multiple elements, some of which are found in nearly all promoters (Table 8.3).

RNA polymerase II starts its “journey” at the TATA region where it binds and travels along the DNA until it reaches the CAP site where the actual synthesis of RNA starts. For example, in the mouse thymidine kinase gene, the TATA box is located at approximately -30 relative to the initiation (+1) site (Figure 1). Eukaryotic promoters are extremely diverse and are difficult to characterize.
