保守的TREX复合体包含UAP56、Aly、CIP29和多亚基THO复合体,在mRNA输出中起作用。最近,一些推测的人类TREX复合物的新组分被质谱鉴定。在这里,我们研究了其中两个PDIP3和ZC11A的功能。我们的数据表明,这两种蛋白质都是共同TREX复合物的组成部分,并在mRNA输出中起作用。最近,我们发现CIP29和Aly都以atp依赖的方式与DEAD盒解旋酶UAP56和TREX复合物结合。我们现在展示PDIP3和ZC11A也是如此。因此,结合之前的工作,我们的数据表明TREX复合物参与多种atp依赖的相互作用。
The conserved TREX complex, which contains UAP56, Aly, CIP29, and the multi-subunit THO complex, functions in mRNA export. Recently, several putative new components of the human TREX complex were identified by mass spectrometry. Here, we investigated the function of two of these, PDIP3 and ZC11A. Our data indicate that both of these proteins are components of a common TREX complex and function in mRNA export. Recently, we found that both CIP29 and Aly associate with the DEAD box helicase UAP56 and with the TREX complex in an ATP-dependent manner. We now show that this is also the case for PDIP3 and ZC11A. Thus, together with previous work, our data indicate that the TREX complex participates in multiple ATP-dependent interactions.
