Nuclear Import of HIV-1 [PDF]

open access: yesViruses, 2021
The delivery of the HIV-1 genome into the nucleus is an indispensable step in retroviral infection of non-dividing cells, but the mechanism of HIV-1 nuclear import has been a longstanding debate due to controversial experimental evidence. It was commonly

Nuclear Import of Yeast Proteasomes [PDF]

open access: yesCells, 2015
Proteasomes are highly conserved protease complexes responsible for the degradation of aberrant and short-lived proteins. In highly proliferating yeast and mammalian cells, proteasomes are predominantly nuclear.

KRT6A Restricts Influenza A Virus Replication by Inhibiting the Nuclear Import and Assembly of Viral Ribonucleoprotein Complex [PDF]

open access: yesViruses
The transcription and replication of the genome of influenza A virus (IAV) take place in the nucleus of infected cells, which is catalyzed by the viral ribonucleoprotein (vRNP) complex. The nuclear import of the vRNP complex and its component proteins is

Viral Targeting of Importin Alpha-Mediated Nuclear Import to Block Innate Immunity [PDF]

open access: yesCells, 2023
Cellular nucleocytoplasmic trafficking is mediated by the importin family of nuclear transport proteins. The well-characterized importin alpha (IMPA) and importin beta (IMPB) nuclear import pathway plays a crucial role in the innate immune response to ...

Nonclassical nuclear localization signals mediate nuclear import of CIRBP [PDF]

open access: yesProceedings of the National Academy of Sciences, 2020
Significance We uncovered a molecular mechanism by which multiple importins regulate nuclear import, phase separation, and stress granule recruitment of an RNA-binding protein.

The nuclear localization signal of CPSF6 governs post-nuclear import steps of HIV-1 infection. [PDF]

open access: yesPLoS Pathogens
The early stages of HIV-1 infection include the trafficking of the viral core into the nucleus of infected cells. However, much remains to be understood about how HIV-1 accomplishes nuclear import and the consequences of the import pathways utilized on ...

A new class of capsid-targeting inhibitors that specifically block HIV-1 nuclear import [PDF]

open access: yesEMBO Molecular Medicine
HIV-1 capsids cross nuclear pore complexes (NPCs) by engaging with the nuclear import machinery. To identify compounds that inhibit HIV-1 nuclear import, we screened drugs in silico on a three-dimensional model of a CA hexamer bound by Transportin-1 (TRN-

Baculovirus Nuclear Import: Open, Nuclear Pore Complex (NPC) Sesame [PDF]

open access: yesViruses, 2013
Baculoviruses are one of the largest viruses that replicate in the nucleus of their host cells. During infection, the rod-shape, 250-nm long nucleocapsid delivers its genome into the nucleus.

Yeast 26S proteasome nuclear import is coupled to nucleus-specific degradation of the karyopherin adaptor protein Sts1 [PDF]

open access: yesScientific Reports
In eukaryotes, the ubiquitin–proteasome system is an essential pathway for protein degradation and cellular homeostasis. 26S proteasomes concentrate in the nucleus of budding yeast Saccharomyces cerevisiae due to the essential import adaptor protein Sts1
