The sequence at -35 (the -35 element) has the consensus sequence TTGACA. The above consensus sequences, while conserved on average, are not found intact in most promoters. On average, only 3 to 4 of the 6 base pairs in each consensus sequence are found in any given promoter.

While techniques such as microarray analysis, RNA interference, and the yeast two-hybrid system can be used to experimentally demonstrate the function of a protein, advances in sequencing technologies have made the rate at which proteins can be experimentally characterized much slower than the rate at which new sequences become available.

Constituent amino-acids can be analyzed to predict secondary, tertiary and quaternary protein structure. This list of protein structure prediction software summarizes notable used software tools in protein structure prediction, including homology modeling, protein threading, ab initio methods, secondary structure prediction, and transmembrane helix and signal peptide prediction.
Promoter activity is a term that encompasses several meanings around the process of gene expression from regulatory sequences —promoters [2] and enhancers. [3] Gene expression has been commonly characterized as a measure of how much, how fast, when and where this process happens. [ 4 ]
The Critical Assessment of Functional Annotation (CAFA) is an experiment designed to provide a large-scale assessment of computational methods dedicated to predicting protein function. [1] Different algorithms are evaluated by their ability to predict the Gene Ontology (GO) terms in the categories of Molecular Function , Biological Process ...
The degree of DNA bending is species and sequence dependent. For example, one study used the adenovirus TATA promoter sequence (5'-CGCTATAAAAGGGC-3') as a model binding sequence and found that human TBP binding to the TATA box induced a 97° bend toward the major groove while the yeast TBP protein only induced an 82° bend. [21]
It is also commonly called the -10 sequence or element, because it is centered roughly ten base pairs upstream from the site of initiation of transcription. The Pribnow box has a function similar to the TATA box that occurs in promoters in eukaryotes and archaea : it is recognized and bound by a subunit of RNA polymerase during initiation of ...
