A comprehensive overview on the crosstalk between microRNAs and viral pathogenesis and infection

open access: yesMedicinal Research Reviews, Volume 45, Issue 2, Page 349-425, March 2025.
Abstract Infections caused by viruses as the smallest infectious agents, pose a major threat to global public health. Viral infections utilize different host mechanisms to facilitate their own propagation and pathogenesis. MicroRNAs (miRNAs), as small noncoding RNA molecules, play important regulatory roles in different diseases, including viral ...

The interaction of RNA helicase DDX3 with HIV-1 Rev-CRM1-RanGTP complex during the HIV replication cycle. [PDF]

open access: yes, 2015
Molecular traffic between the nucleus and the cytoplasm is regulated by the nuclear pore complex (NPC), which acts as a highly selective channel perforating the nuclear envelope in eukaryotic cells.

Crystal structure of human CRM1, covalently modified by 2‐mercaptoethanol on Cys528, in complex with RanGTP

open access: yes, 2022
CRM1 is a nuclear export receptor that has been intensively targeted over the last decade for the development of antitumor and antiviral drugs. Structural analysis of several inhibitor compounds bound to CRM1 revealed that their mechanism of action ...

Ciliary entry of the kinesin-2 motor KIF17 is regulated by importin-beta2 and RanGTP [PDF]

open access: yes, 2010
The biogenesis, maintenance and function of primary cilia are controlled through intraflagellar transport (IFT) driven by two kinesin-2 family members, the heterotrimeric KIF3A/KIF3B/KAP complex and the homodimeric KIF17 motor. How these motors and their

Steady-State Nuclear Localization of Exportin-t Involves RanGTP Binding and Two Distinct Nuclear Pore Complex Interaction Domains

open access: yes, 2002
Vertebrate tRNA export receptor exportin-t (Xpo-t) binds to RanGTP and mature tRNAs cooperatively to form a nuclear export complex. Xpo-t shuttles bidirectionally through nuclear pore complexes (NPCs) but is mainly nuclear at steady state.

The asymmetric distribution of the constituents of the Ran system is essential for transport into and out of the nucleus. [PDF]

open access: yes, 1997
The GTPase Ran is essential for nuclear import of proteins with a classical nuclear localization signal (NLS). Ran's nucleotide‐bound state is determined by the chromatin‐bound exchange factor RCC1 generating RanGTP in the nucleus and the cytoplasmic ...

Mechanism of RanGTP dependent microtubule assembly during mitosis

open access: yes
During mitosis, spindle assembly involves different sources of microtubules including centrosomes and chromosomes. While the role of centrosomes has been extensively studied, we still do not fully understand how chromosomes trigger microtubule assembly ...

Aurora A Kinase-Coated Beads Function as Microtubule-Organizing Centers and Enhance RanGTP-Induced Spindle Assembly

open access: yes, 2005
SummaryThe roles of the kinase Aurora A (AurA) in centrosome function and spindle assembly [1–3] have been established in Drosophila [4, 5], C. elegans [6], and Xenopus egg extracts [7–9].
