TBP binding protein associated factor 15 (TAF15) is a member of the multifunctional FET (FUS, EWS, and TAF15) family of proteins that bind both DNA and RNA and may be important for transcriptional regulation and RNA processing (1,2). Research studies show that FET family proteins, including TAF15, can be found as oncogenic fusion proteins with transcription factors in a variety of cancers. The fusion protein consists of the FET protein amino-terminal transcription activation domain and the transcription factor DNA binding domain, creating an aberrant transcription factor with potent transactivation potential (1-3). TAF15 can be part of a subset of the transcription factor IID (TFIID) complex, indicating that it may form a transcription pre-initiation complex at active genes, even if it is not considered a canonical TAF (4,5). Additional studies suggest roles for TAF15 in RNA splicing through its association with U1 small nuclear RNA and in regulation of cell cycle regulatory gene expression through a mechanism involving miRNA biosynthesis (6,7).

TBP binding protein associated factor 15 (TAF15)是多功能性FET (FUS, EWS, 以及TAF15)蛋白家族的成员之一,该蛋白家族能与DNA 和 RNA结合,可能对于转录调控以及RNA加工都非常重要(1,2)。研究发现FET家族蛋白,包括TAF15,再许多癌症中,可作为转录因子的肿瘤发生融合蛋白。该融合蛋白由FET蛋白氨基末端转录激活结构域和转录因子DNA结合结构域组成,产生一个畸变的具有有效转录激活潜能的转录因子(1-3)。TAF15可作为transcription factor IID (TFIID) complex的一个子集的一部分,这意味着它可能能够在活化基因上形成一个转录起始前复合物,即使它并不被认为是一个规范的TAF(4,5)。还有一些研究表明,TAF15可以通过其与U1 small nuclear RNA的结合在RNA剪接中发挥作用,并且还能通过一种参与miRNA生物合成的机制来调节细胞周期调控基因的表达(6,7)。
