Generally, the TATA box is found at RNA polymerase II promoter regions, although some in vitro studies have demonstrated that RNA polymerase III can recognize TATA sequences. [25] This cluster of RNA polymerase II and various transcription factors is known as the basal transcriptional … Zobacz więcej In molecular biology, the TATA box (also called the Goldberg–Hogness box) is a sequence of DNA found in the core promoter region of genes in archaea and eukaryotes. The bacterial homolog of the TATA box is called the Zobacz więcej Location 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 … Zobacz więcej Role in transcription initiation The TATA-box is the site of preinitiation complex formation, which is the first step in transcription … Zobacz więcej Mutations to the TATA box can range from a deletion or insertion to a point mutation with varying effects based on the gene that has been mutated. … Zobacz więcej Discovery The TATA box was the first eukaryotic core promoter motif to be identified in 1978 by American biochemist David Hogness while … Zobacz więcej Sequence and prevalence The TATA box is a component of the eukaryotic core promoter and generally contains the consensus sequence 5'-TATA(A/T)A(A/T)-3'.
