N6-甲基腺苷(m6 A)是真核生物mRNA中最丰富的内部修饰。这种修饰以前已经显示出改变mRNA的输出动力学,尽管围绕这种现象的分子细节仍然知之甚少。TREX mRNA输出复合物向mRNA的募集由转录、5′加帽和前体mRNA剪接驱动。在这里,我们确定了人类细胞中的第四种机制,驱动TREX与涉及m6 A甲基化酶复合物的mRNA的关联。我们表明,m6 A复合物招募TREX m6 A修饰的mRNA,这一过程是必不可少的,他们的有效出口。TREX还刺激m6 A阅读器蛋白YTHDC 1向mRNA的募集,并且m6 A复合物影响TREX与YTHDC 1的相互作用。总之,我们的研究揭示了TREX在m6 A修饰的mRNA的输出中的关键作用。
N6-methyladenosine (m6A) is the most abundant internal modification of eukaryotic mRNA. This modification has previously been shown to alter the export kinetics for mRNAs though the molecular details surrounding this phenomenon remain poorly understood. Recruitment of the TREX mRNA export complex to mRNA is driven by transcription, 5′ capping and pre-mRNA splicing. Here we identify a fourth mechanism in human cells driving the association of TREX with mRNA involving the m6A methylase complex. We show that the m6A complex recruits TREX to m6A modified mRNAs and this process is essential for their efficient export. TREX also stimulates recruitment of the m6A reader protein YTHDC1 to the mRNA and the m6A complex influences the interaction of TREX with YTHDC1. Together our studies reveal a key role for TREX in the export of m6A modified mRNAs.
