TATA box

TATA box. An adenine- and thymine-rich promoter sequence located 25-30 bp upstream of a gene, which is the binding site of RNA polymerase.

TATA box
A conserved sequence 25 to 30 base pairs upstream from the site for transcription in many but not all genes; binding site for general factors involved in initiation of transcription. In prokaryotes the analogous is called Pribnow box.

TATA box: A sequence found in the promoter (part of the 5' flanking region) of many genes.

Usually associated with transcription-initiation regions of (housekeeping) genes transcribed at low rates that do not contain a TATA box.

most have the Goldberg Hogness or tATA box that is centred around position 25 and has the consensus sequence 5' TATAAAA 3'. Several promoters have a cAAT box around 90 with the consensus sequence 5' GGCCAATCT 3'.

Many eukaryotic promoters, but by no means all, contain a TATA box (sequence TATAAA), which in turn binds a TATA binding protein which assists in the formation of the RNA polymerase transcriptional complex.

Histones act in gene regulation. Histones can undergo posttranslational modifications. These modifications can play a role in gene regulation in an epigenetic manner. Regulation occurs at the TATA box.
