TFIIB (also known as GTF2B, TF2B and general transcription factor IIB) is a ubiquitously expressed transcription factor that plays a central role in the assembly of the transcription pre-initiation complex through direct recruitment of RNA polymerase II (1,2). TFIIB functions as a bridge between promoter-bound TFIID and RNA polymerase II. In addition to interacting with promoter-bound TFIID and TFIIA, TFIIB makes extensive contacts with the core promoter via two independent DNA-binding modules. TFIIB may also be a target of transcriptional activator proteins that act to stimulate pre-initiation complex assembly.

TFIIB (也称为GTF2B、TF2B和general transcription factor IIB)是一个广泛表达的转录因子,它通过直接招募RNA polymerase II在转录起始前复合物的装配中起着关键作用(1,2)。TFIIB功能作为束缚在启动子上的TFIID和RNA polymerase II之间的一个桥梁作用。除了与束缚在启动子TFIID和TFIIA相互作用之外,TFIIB蛋白通过两个独立的DNA结合模板使得与中心启动子有广泛接触。TFIIB蛋白也可能是一个转录激活蛋白的靶蛋白,该蛋白可以刺激起始前复合物的装配。
