Editing TATA box (section)

=== Analogous sequences ===
In bacteria, promoter regions may contain a [[Pribnow box]], which serves an analogous purpose to the eukaryotic TATA box. The Pribnow box has a 6 bp region centered around the -10 position and an 8-12 bp sequence around the -35 region that are both conserved.<ref name=":12" />

A [[CAAT box]] (also CAT box) is a region of nucleotides with the following consensus sequence: 5’ GGCCAATCT 3’. The CAAT box is located about 75-80 bases upstream of the transcription initiation site and about 150 bases upstream of the TATA box. It binds [[transcription factor]]s (CAAT TF or CTFs) and thereby stabilizes the nearby [[Transcription preinitiation complex|preinitiation complex]] for easier binding of [[RNA polymerase]]s.&nbsp;CAAT boxes are rarely found in genes that express proteins ubiquitous in all cell types.<ref name=":12" />
