Impact of Nuclear Export Pathway on Cytoplasmic HIV-1 RNA Transport Mechanism and Distribution
HIV-1 full-length RNA (referred to as HIV-1 RNA here) serves as the viral genome in virions and as a template for Gag/Gag-Pol translation. We previously showed that HIV-1 RNA, which is exported via the CRM1 pathway, travels in the cytoplasm mainly ...

Channel nuclear pore complex subunits are required for transposon silencing in Drosophila
The nuclear pore complex (NPC) is the principal gateway between nucleus and cytoplasm that enables exchange of macromolecular cargo. Composed of multiple copies of ~30 different nucleoporins (Nups), the NPC acts as a selective portal, interacting with ...

Structural basis for high-order complex of SARNP and DDX39B to facilitate mRNP assembly
Summary: mRNA in eukaryotic cells is packaged into highly compacted ribonucleoprotein particles (mRNPs) in the nucleus and exported to the cytoplasm for translation.

Localization of nucleoporin Tpr to the nuclear pore complex is essential for Tpr mediated regulation of the export of unspliced RNA. [PDF]
Nucleoporin Tpr is a component of the nuclear pore complex (NPC) that localizes exclusively to intranuclear filaments. Tpr functions as a scaffolding element in the nuclear phase of the NPC and plays a role in mitotic spindle checkpoint signalling ...

RNA export through the nuclear pore complex is directional
There is little information on export directionality of RNA passing through the nuclear pore complex in human cells. Here, the authors examine single RNA molecules in transit, to demonstrate 5’-first directionality for the export of mRNA and lncRNA.

hnRNPA3 regulates hESCs pluripotency through modulating mRNA export [PDF]
Objective To explore the biological function of RNA binding protein heterogeneous nuclear ribonucleoprotein A3(hnRNPA3) in the maintenance of pluripotency of human embryonic stem cells(hESCs) and to reveal its new mechanism in RNA transport.

Competitive and cooperative interactions mediate RNA transfer from herpesvirus saimiri ORF57 to the mammalian export adaptor ALYREF. [PDF]
The essential herpesvirus adaptor protein HVS ORF57, which has homologs in all other herpesviruses, promotes viral mRNA export by utilizing the cellular mRNA export machinery.

Once transcribed, the nascent full-length RNA of HIV-1 must travel to the appropriate host cell sites to be translated or to find a partner RNA for copackaging to form newly generated viruses. In this report, we sought to delineate the location where HIV-

Comprehensive analysis of the circadian nuclear and cytoplasmic transcriptome in mouse liver.
In eukaryotes, RNA is synthesised in the nucleus, spliced, and exported to the cytoplasm where it is translated and finally degraded. Any of these steps could be subject to temporal regulation during the circadian cycle, resulting in daily fluctuations ...

RNA-guided assembly of Rev-RRE nuclear export complexes
HIV replication requires nuclear export of unspliced and singly spliced viral transcripts. Although a unique RNA structure has been proposed for the Rev-response element (RRE) responsible for viral mRNA export, how it recruits multiple HIV Rev proteins ...
