Description
TFIIB is a ubiquitous factor required for transcription initiation by RNA polymerase II. Studies suggest that TFIIB serves as a bridge between the “TATA”-binding factor (TFIID) and RNA polymerase II during pre-initiation complex assembly and that TFIIB can be a target of acidic activators. An essential component of the machinery that transcribes protein-coding genes, the three-dimensional structure of the human TFIIB appears to consist of two direct repeats that adopt similar alpha-helical folds, conferring pseudo-twofold symmetry. An extensive, central basic surface, including an amphipathic alpha helix, is critical to the function of TFIIB as a bridge between the TBP-promoter complex and transcription factors. TFIIB has a calculated molecular weight of 33kDa and has been reported to be observed to migrate between 33-40kDa.
