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. Many such tools have been developed. [49] A bacterial promoter region is located before the -35 and -10 Consensus sequences.
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 ...

This is because a gene with an active Inr is less dependent on a functional TATA box or additional promoters. [8] Although Inr element varies between promoters, the sequence is highly conserved between humans and yeast. [8] An analysis of 7670 transcription start sites showed that roughly 40% had an exact match to the BBCA+1BW Inr sequence.
The promoter region is a prime regulator of transcription. Promoter regions regulate transcription of all genes within bacteria. As a result of their involvement, the sequence of base pairs within the promoter region is significant; the more similar the promoter region is to the consensus sequence, the tighter RNA polymerase will be able to bind.
It is involved in ensuring the sigma factor will only bind the promoter when it is complexed with the RNA polymerase. [7] Domains 2-4 each interact with specific promoter elements and with RNAP. Region 2.4 recognizes and binds to the promoter −10 element (called the "Pribnow box"). Region 4.2 recognizes and binds to the promoter −35 element ...

Promoter sequences vary between bacteria and eukaryotes. In eukaryotes, the TATA box is located 25 base pairs upstream of the start site that Rpb4 /Rbp7 use to initiate transcription . In metazoans , the TATA box is located 30 base pairs upstream of the transcription start site. [ 5 ]
