| Background | TATA-binding protein (TBP) is a ubiquitously expressed nuclear protein that functions at the core of the general transcription factor protein complex TFIID (1-3). TFIID, which contains TBP and 13 TBP-associated factors (TAFs), contributes to the formation of the transcription pre-initiation complex, an assembly of multiple protein complexes (TFIIA, TFIIB, TFIIE, TFIIF, TFIIH, and RNA polymerase II) that bind to a gene promoter during the initiation of transcription (1-3). Once the pre-initiation complex is formed, RNA polymerase II becomes competent for elongation and transcribes the body of a gene. TBP functions in the recruitment of TFIID by binding to the TATA-box sequence found approximately 25 base pairs upstream of the transcription start site of many protein-coding genes. In addition, many transcriptional activator proteins interact with TBP and various TAF proteins to facilitate recruitment of TFIID and formation of the pre-initiation complex. |

Purification of the human TATA-Binding Protein, TBP
The TATA-binding protein TBP plays a central role in eukaryotic transcription initiation (1 , 2 ). TBP binds to the promoter consensus sequence TATAAA, located approx 30 nucleotides upstream of the transcriptional start site. Once bound, TBP
Using FRET to Monitor Protein-Induced DNA Bending: The TBP-TATA Complex as a Model System
Proteins that bind to DNA can elicit changes in DNA conformation, such as bending and looping, which are important signals for later events such as transcription. TATA-binding protein (TBP) is one example of a protein that elicits
