Nuclear transport maintenance of USP22-AR by Importin-7 promotes breast cancer progression

open access: yesCell Death Discovery, 2023
The translocation of biological macromolecules between cytoplasm and nucleus is of great significance to maintain various life processes in both normal and cancer cells.

Importin-Mediated Pathological Tau Nuclear Translocation Causes Disruption of the Nuclear Lamina, TDP-43 Mislocalization and Cell Death

open access: yesFrontiers in Molecular Neuroscience, 2022
Tau is a cytosolic protein that has also been observed in the nucleus, where it has multiple proposed functions that are regulated by phosphorylation.

Importin binding mediates the intramolecular regulation of anillin during cytokinesis

open access: yesMolecular Biology of the Cell, 2020
Cytokinesis occurs by the ingression of an actomyosin ring that cleaves a cell into two daughters. This process is tightly controlled to avoid aneuploidy, and we previously showed that active Ran coordinates ring positioning with chromatin. Active Ran is

Functional requirement of the Arabidopsis importin-α nuclear transport receptor family in autoimmunity mediated by the NLR protein SNC1

open access: yesbioRxiv, 2020
IMPORTIN-α3/MOS6 (MODIFIER OF SNC1, 6) is one of nine importin-α isoforms in Arabidopsis that recruit nuclear localization signal (NLS)-containing cargo proteins to the nuclear import machinery.

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

open access: yesFrontiers 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-9 regulates chromosome segregation and packaging in Drosophila germ cells

open access: yesbioRxiv, 2020
Germ cells undergo distinct nuclear processes as they differentiate into gametes. While these events must be coordinated to ensure proper maturation, the stage-specific transport of proteins in and out of germ cell nuclei remains incompletely understood.

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

open access: yesPLoS 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.

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

open access: yeseLife, 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

NF-κB is transported into the nucleus by importin α3 and importin α4

open access: yes, 2005
NF-{kappa}B transcription factors are retained in the cytoplasm in an inactive form until they are activated and rapidly imported into the nucleus. We identified importin {alpha}3 and importin {alpha}4 as the main importin {alpha} isoforms mediating TNF-{

Importin α: functions as a nuclear transport factor and beyond

open access: yesProceedings of the Japan Academy. Series B, Physical and biological sciences, 2018
Nucleocytoplasmic transport is an essential process in eukaryotes. The molecular mechanisms underlying nuclear transport that involve the nuclear transport receptor, small GTPase Ran, and the nuclear pore complex are highly conserved from yeast to humans.
