关于 TAF11

功能概要

RNA 聚合酶 II 启动转录需要 70 多种多肽的活性。协调这些活动的蛋白质是转录因子 IID (TFIID) ，它与核心启动子结合以正确定位聚合酶，充当组装转录复合物其余部分的支架，并充当调节信号的通道。 TFIID 由 TATA 结合蛋白 (TBP) 和一组称为 TBP 相关因子或 TAF 的进化保守蛋白组成。 TAF 可能参与基础转录，充当共激活因子，在启动子识别中发挥作用或修饰一般转录因子 (GTF) 以促进复杂的组装和转录起始。该基因编码 TFIID 的一个小亚基，该亚基存在于所有 TFIID 复合物中并与 TBP 相互作用。该亚基还与另一个小亚基 TAF13 相互作用，形成结构类似于组蛋白核心结构的异二聚体。已发现该基因的两个转录本变体编码不同的亚型。[RefSeq 提供，2012 年 7 月]

Initiation of transcription by RNA polymerase II requires the activities of more than 70 polypeptides. The protein that coordinates these activities is transcription factor IID (TFIID), which binds to the core promoter to position the polymerase properly, serves as the scaffold for assembly of the remainder of the transcription complex, and acts as a channel for regulatory signals. TFIID is composed of the TATA-binding protein (TBP) and a group of evolutionarily conserved proteins known as TBP-associated factors or TAFs. TAFs may participate in basal transcription, serve as coactivators, function in promoter recognition or modify general transcription factors (GTFs) to facilitate complex assembly and transcription initiation. This gene encodes a small subunit of TFIID that is present in all TFIID complexes and interacts with TBP. This subunit also interacts with another small subunit, TAF13, to form a heterodimer with a structure similar to the histone core structure. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2012]
