The TATA box was the first eukaryotic core promoter motif to be identified in 1978 by American biochemist David Hogness [1] while he and his graduate student, Michael Goldberg were on sabbatical at the University of Basel in Switzerland. [7]
The TATA-binding protein (TBP) is a general transcription factor that binds to a DNA sequence called the TATA box. This DNA sequence is found about 30 base pairs upstream of the transcription start site in some eukaryotic gene promoters .
The B recognition element (BRE) is a DNA sequence found in the promoter region of most [clarification needed] genes in eukaryotes and Archaea. [1] [2] The BRE is a cis-regulatory element that is found immediately near TATA box, and consists of 7 nucleotides. There are two sets of BREs: one (BREu) found immediately upstream of the TATA box, with ...
The archaeal promoter resembles an eukaryotic one: a TATA box (at -26/-27) and an upstream BRE (at -33/-34) are commonly found, binding to TBP and TFB (homolog of TFIIB). [3] There are also occasionally an initiator element (INR) near the transcription start site [TSS], and a promoter proximal element (PPE) between BRE-TATA and TSS.
A common basal promoter is the TATAAAAAA sequence known as the TATA box. The TATA box is a complex with several different proteins including transcription factor II D (TFIID) which includes the TATA-binding protein (TBP) that binds to the TATA box along with 13 other proteins that bind to TBP. The TATA box binding proteins also include the ...
The Inr element for core promoters was found to be more prevalent than the TATA box in eukaryotic promoter domains. [11] In a study of 1800+ distinct human promoter sequences it was found that 49% contain the Inr element while 21.8% contain the TATA box. [11] Out of those sequences with the TATA box, 62% contained the Inr element as well.
In eukaryotes, the 5′ flanking region has a complex set of regulatory elements such as enhancers, silencers, and promoters. The primary promoter element in eukaryotes is the TATA box. Other promoter elements found in eukaryotic 5′ flanking regions include initiator elements, downstream core promoter element, CAAT box, and the GC box. [1]
In molecular biology, a GC box, also known as a GSG box, [1] is a distinct pattern of nucleotides found in the promoter region of some eukaryotic genes. The GC box is upstream of the TATA box, and approximately 110 bases upstream from the transcription initiation site.
