MxB impedes the NUP358-mediated HIV-1 pre-integration complex nuclear import and viral replication cooperatively with CPSF6

open access: yesRetrovirology, 2020
Background The human myxovirus resistance 2 (Mx2/MxB) protein was originally found to regulate cytoplasmic-nuclear transport but was recently reported to restrict HIV-1 replication by binding to HIV-1 capsid (CA), preventing uncoating, the nuclear import

CRISPR/Cas9-Induced Mutagenesis Corroborates the Role of Transportin-SR2 in HIV-1 Nuclear Import

open access: yesMicrobiology Spectrum, 2021
To infect nondividing cells, HIV-1 needs to cross the nuclear membrane. The importin transportin-SR2 (TRN-SR2 or transportin-3) has been proposed to mediate HIV-1 nuclear import, but the detailed mechanism remains unresolved.

Nuclear Import of Adeno-Associated Viruses Imaged by High-Speed Single-Molecule Microscopy

open access: yesViruses, 2021
Understanding the detailed nuclear import kinetics of adeno-associated virus (AAV) through the nuclear pore complex (NPC) is essential for the application of AAV capsids as a nuclear delivery instrument as well as a target for drug development.

Phospholipid scramblase 1 interacts with influenza A virus NP, impairing its nuclear import and thereby suppressing virus replication. [PDF]

open access: yesPLoS Pathogens, 2018
Transcription and replication of the influenza A virus (IAV) genome occur in the nucleus of infected cells and are carried out by the viral ribonucleoprotein complex (vRNP).

Nuclear protein import [PDF]

open access: yesCurrent Opinion in Cell Biology, 1997
The defining feature of eukaryotic organisms is the cell nucleus. All nuclear proteins are synthesized in the cytoplasm and need to be imported through the nuclear pore complexes (NPCs) into the nucleus. Import can be directed by various signals, of which the classical nuclear localization signal (NLS) and the M9 import signal are the best ...

RAM function is dependent on Kapβ2-mediated nuclear entry [PDF]

open access: yes, 2014
Eukaryotic gene expression is dependent on the modification of the first transcribed nucleotide of pre-mRNA by the addition of the 7-methylguanosine cap.

Nuclear import of PKCδ is required for apoptosis: identification of a novel nuclear import sequence [PDF]

open access: yesThe EMBO Journal, 2002
We have shown previously that protein kinase Cdelta (PKCdelta) is required for mitochondrial-dependent apoptosis. Here we show that PKCdelta is imported into the nucleus of etoposide-treated cells, that nuclear import is required for apoptosis and that it is mediated by a nuclear localization signal (NLS) in the C-terminus of PKCdelta.

Intermolecular masking of the HIV-1 Rev NLS by the cellular protein HIC: Novel insights into the regulation of Rev nuclear import

open access: yesRetrovirology, 2011
Background The HIV-1 regulatory protein Rev, which is essential for viral replication, mediates the nuclear export of unspliced viral transcripts. Rev nuclear function requires active nucleocytoplasmic shuttling, and Rev nuclear import is mediated by the

p53 stabilization: the importance of nuclear import [PDF]

open access: yesCell Death & Differentiation, 2010
In response to cellular stress, the p53 tumor suppressor protein is stabilized as a result of inactivation of ubiquitin-mediated degradation. The p53 protein rapidly accumulates in the nucleus, where it functions as a transcription factor. Although the regulation of p53 stability has been studied extensively, the subcellular compartment in which p53 ...
