为了确定哪些转录产物应该到达细胞质进行翻译,真核细胞已经建立了通过核孔复合体(NPC)调节选择性mRNA输出的机制。核篮子是NPC的一个亚结构,突出到核质中,被认为是一个稳定的平台,在那里mRNA-蛋白质复合体(MRNP)在出口之前进行重新排列并接受质量控制,确保只有成熟的mRNAs才能到达细胞质。在这里,我们使用蛋白质组学、遗传学、活细胞和单分子分辨显微镜方法在萌芽酵母中证明篮子的形成依赖于RNA聚合酶II的转录和随后的mRNP加工。我们进一步证明,虽然所有的NPC都可以与Mlp1结合,但篮子只组装在核质NPC的子集上,并且这些含有篮子的NPC与不同的蛋白质和RNA相互作用组有关。综上所述,我们的数据指向NPC的异质性和通过核篮组装在萌芽酵母中使NPC功能化的依赖于RNA的机制。
To determine which transcripts should reach the cytoplasm for translation, eukaryotic cells have established mechanisms to regulate selective mRNA export through the nuclear pore complex (NPC). The nuclear basket, a substructure of the NPC protruding into the nucleoplasm, is thought to function as a stable platform where mRNA-protein complexes (mRNPs) are rearranged and undergo quality control prior to export, ensuring that only mature mRNAs reach the cytoplasm. Here, we use proteomic, genetic, live-cell, and single-molecule resolution microscopy approaches in budding yeast to demonstrate that basket formation is dependent on RNA polymerase II transcription and subsequent mRNP processing. We further show that while all NPCs can bind Mlp1, baskets assemble only on a subset of nucleoplasmic NPCs, and these basket-containing NPCs associate a distinct protein and RNA interactome. Taken together, our data points towards NPC heterogeneity and an RNA-dependent mechanism for functionalization of NPCs in budding yeast through nuclear basket assembly.
