Structure
The structure of the TBP has an internal pseudo-symmetry which contains two 88- amino acid repeats. This structure attaches to a DNA structure of deformity in the helix. The DNA structure's minor groove is opened wide to have complete access for the TBP to bind within it.
Function
The TATA-Binding protein, TBP, is a factor in the process of Transcription within Eukaryotes. This binding protein is a subunit in the family of TFIID. The function of the TBP is to bind to a DNA sequence which is the TATA box. This allows RNA Polymerase II to bind to the promoter. This is the beginning of the process of Transcription.
Relevance
The TATA-Binding Protein is relevant to everyday life because humans contain this specific protein as well with or without a promoter. This process is happening in multiple tissues and cells at a time.
Interesting Facts about the TBP
-The first ever for the TBP was found in fruit flies, specifically Drosophila flies.
-This is not the same idea in prokaryotes. Prokaryotes have a different concept because it is a Pribnow box instead of a TATA box.
-Another name for the TATA box is the Goldberg- Hogness box.
