Structural insight into TPX2-stimulated microtubule assembly [PDF]

, 2017
During mitosis and meiosis, microtubule (MT) assembly is locally upregulated by the chromatin-dependent Ran-GTP pathway. One of its key targets is the MT-associated spindle assembly factor TPX2.

Subcellular Localization of Epstein–Barr Virus BLLF2 and Its Underlying Mechanisms

Frontiers in Microbiology, 2021
Epstein–Barr virus (EBV), the pathogen of several human malignancies, encodes many proteins required to be transported into the nucleus for viral DNA reproduction and nucleocapsids assembly in the lytic replication cycle.

Importin α1 is required for nuclear import of herpes simplex virus proteins and capsid assembly in fibroblasts and neurons.

PLoS Pathogens, 2018
Herpesviruses are large DNA viruses which depend on many nuclear functions, and therefore on host transport factors to ensure specific nuclear import of viral and host components. While some import cargoes bind directly to certain transport factors, most

Genome-scale analysis identifies paralog lethality as a vulnerability of chromosome 1p loss in cancer. [PDF]

, 2018
Functional redundancy shared by paralog genes may afford protection against genetic perturbations, but it can also result in genetic vulnerabilities due to mutual interdependency1-5.

Conserved arginines of bovine adenovirus-3 33K protein are important for transportin-3 mediated transport and virus replication. [PDF]

PLoS ONE, 2014
The L6 region of bovine adenovirus (BAdV)-3 encodes a spliced protein designated 33K. The 33K specific sera detected five major proteins and three minor proteins in transfected or virus infected cells, which could arise by internal initiation of ...

A specific role for importin-5 and NASP in the import and nuclear hand-off of monomeric H3

eLife, 2022
Core histones package chromosomal DNA and regulate genomic transactions, with their nuclear import and deposition involving importin-β proteins and a dedicated repertoire of histone chaperones. Previously, a histone H3-H4 dimer has been isolated bound to

Crystal structure of human importin-α1 (Rch1), revealing a potential autoinhibition mode involving homodimerization.

PLoS ONE, 2015
In this study, we determined the crystal structure of N-terminal importin-β-binding domain (IBB)-truncated human importin-α1 (ΔIBB-h-importin-α1) at 2.63 Å resolution. The crystal structure of ΔIBB-h-importin-α1 reveals a novel closed homodimer.

Mitotic spindle scaling during Xenopus development by kif2a and importin α. [PDF]

, 2012
Early development of many animals is characterized by rapid cleavages that dramatically decrease cell size, but how the mitotic spindle adapts to changing cell dimensions is not understood.

Importin α5 negatively regulates importin β1-mediated nuclear import of Newcastle disease virus matrix protein and viral replication and pathogenicity in chicken fibroblasts

Virulence, 2018
The matrix (M) protein of Newcastle disease virus (NDV) is demonstrated to localize in the nucleus via intrinsic nuclear localization signal (NLS), but cellular proteins involved in the nuclear import of NDV M protein and the role of M's nuclear ...
