B-TATA binding protein-associated factor 1 (BTAF1) is a human homolog of the yeast protein modifier of transcription 1 (MOT1) (1). BTAF1 negatively regulates transcription through interaction with TATA binding protein (TBP), an important component of the B-TFIID complex (2,3). BTAF1 is a member of the SNF2 family of ATPases that utilizes ATP to remove TBP from B-TFIID, thereby preventing formation of the transcription pre-initiation complex (PIC) (3-5). BTAF1 actively removes TBP from DNA, which prevents non-specific TBP-DNA interactions and promotes disassembly of inactive forms of the PIC. This activity is thought to be critical for maintaining a pool of free TBP that is necessary for the assembly of the PIC during transcription activation (6,7).

B-TATA binding protein-associated factor 1 (BTAF1)是一个酵母蛋白modifier of transcription 1 (MOT1)的人源同系物(1)。BTAF1通过与TATA binding protein (TBP)相互作用负性调节转录,而TATA binding protein (TBP)是B-TFIID复合物的一个重要成分(2,3)。BTAF1是ATPases的SNF2家族成员,该激酶能利用ATP去从B-TFIID上移除TBP,因此抑制转录前起始复合物(PIC)的形成 (3-5)。BTAF1积极地移除DNA上的TBP,这抑制非特异性TBP-DNA相互作用,并且促进PIC的非活性形式的分解。这活性被认为对于维持一批游离的TBP是至关重要的,而游离的TBP对于在转录激活期间PIC的装配是必要的(6,7)。
