Kutach and Kadonaga (2000). c, SVRscp1 models trained with HARPE data for the DPR with the SCP1 (TATA-containing) promoter cassette (promoter background) are reproducible. The models in this figure were built by using default parameters for SVR training. The absence of TATA boxes in bidirectional promoters suggests that TATA boxes play a role in determining the directionality of promoters, but counterexamples of bidirectional promoters do possess TATA boxes and unidirectional promoters without them indicates that they cannot be the only factor. Mediator (coactivator) (a complex usually consisting of about 26 proteins in an interacting structure) communicates regulatory signals from enhancer DNA-bound transcription factors directly to the RNA polymerase II (pol II) enzyme bound to the promoter.

Nat. Core promoter elements: the combinatorial code of precise transcription initiation The Pol II core promoter is composed of short DNA sequences that are referred to … g, Most variants are present and detectable in biological replicates. [36], Although the term "bidirectional promoter" refers specifically to promoter regions of mRNA-encoding genes, luciferase assays have shown that over half of human genes do not have a strong directional bias. Gene promoters are typically located upstream of the gene and can have regulatory elements several kilobases away from the transcriptional start site (enhancers). It leverages the preferential occurrence of certain DNA motifs at characteristic distances from the TSS. These sequences were then used in the performance assessment. Intermediate variants that were between the top and bottom groups were not included. 2 Further characterization of the HARPE assay and modification of the HARPE assay to include the analysis of the upstream TATA box element.

A wide variety of algorithms have been developed to facilitate detection of promoters in genomic sequence, and promoter prediction is a common element of many gene prediction methods. The SVRc (SVR from cell-based data) scores derived from these data correlate with measured transcription strengths in cells (with data that are independent of the SVRc training data) (representative experiment, n = 2 biologically independent samples). As promoters are typically immediately adjacent to the gene in question, positions in the promoter are designated relative to the transcriptional start site, where transcription of DNA begins for a particular gene (i.e., positions upstream are negative numbers counting back from -1, for example -100 is a position 100 base pairs upstream).
