What is TBP in genetics?
The TBP gene provides instructions for making a protein called the TATA box binding protein. This protein is active in cells and tissues throughout the body, where it plays an essential role in regulating the activity of most genes.
What does TATA box detect?
The TATA Box The TATA-binding protein (sometimes referred to as TBP) recognizes this TATA sequence and binds to it, creating a landmark that marks the start site of transcription. Transcription factors bound to short pieces of DNA: TFIIB (top), TFIIA (middle), and NC2 (bottom).
Which among the following factors recognizes TATA box of DNA?
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. This cluster of RNA polymerase II and various transcription factors is known as the basal transcriptional complex (BTC).

Why does TBP bind to minor groove?
The TBP represents one of the few protein families that use an extended β-sheet to bind target DNA. This intercalation causes a broad opening of the minor groove and large-scale distortion of the DNA which can then accommodate the twisted structure of the large sheet.
Where does TBP bind DNA?
The TATA-binding protein (TBP) is a general transcription factor that binds specifically 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.
How does TBP bind to TATA box?
DNA-protein interactions When TBP binds to a TATA box within the DNA, it distorts the DNA by inserting amino acid side-chains between base pairs, partially unwinding the helix, and doubly kinking it. The distortion is accomplished through a great amount of surface contact between the protein and DNA.
What happens if the TATA box is deleted?
Deletion of a TATA box results in loss of the corresponding cap sites. An insertion of 7 bp between the right TATA box and corresponding cap sites results in a shift of the position of the cap sites, so that the original distance of TATA box to cap sites is conserved as much as possible.
