C9orf72 arginine-rich dipeptide repeat proteins disrupt karyopherin-mediated nuclear import

eLife, 2020
Disruption of nucleocytoplasmic transport is increasingly implicated in the pathogenesis of neurodegenerative diseases, including ALS caused by a C9orf72 hexanucleotide repeat expansion. However, the mechanism(s) remain unclear.

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

Cells, 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 ...

The functions of herpesvirus shuttling proteins in the virus lifecycle

Frontiers in Microbiology
During viral infection, the transport of various proteins between the nucleus and cytoplasm plays an important role in the viral lifecycle. Shuttling proteins are key factors in the transmission of nucleocytoplasmic information within cells and usually ...

Differential interactome mapping of aggregation prone/prion-like proteins under stress: novel links to stress granule biology

Cell & Bioscience, 2023
Background Aberrant stress granules (SGs) are emerging as prime suspects in the nucleation of toxic protein aggregates. Understanding the molecular networks linked with aggregation-prone proteins (prion protein, synuclein, and tau) under stressful ...

A Review of the Role of Shuttling Proteins in Herpesvirus Replication and Pathogenesis

Al-Kitab Journal for Pure Sciences
 Herpesviruses are complex DNA viruses that rely on host-cell machinery for replication and pathogenesis. One critical aspect of their lifecycle involves the transport of viral and host proteins between the nucleus and cytoplasm.

Perturbations in Traffic: Aberrant Nucleocytoplasmic Transport at the Heart of Neurodegeneration

Cells, 2018
Neurodegenerative diseases, such as amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Huntington’s disease (HD), are characterized by intracellular aggregation of proteins.

Evaluating the involvement of autolysosomes in the nuclear translocation of fluorescent proteins

FEBS Open Bio, EarlyView.
Endogenously expressed fluorescent proteins can be degraded by autophagy and transported to cell nuclei via the nuclear pore complex. But in some cell lines, for example, HeLa cells which are positive for immunoreactivity of a receptor ligand, such as UCN I, in cell nuclei, fusion of autolysosome with the nuclear envelope is involved in the nuclear ...

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Desmin’s conformational modulation by hydrophobicity

Türk Biyokimya Dergisi
Nucleocytoplasmic transport is one of the key features in regulation of cellular physiology. Developing a better understanding of the molecular mechanism underlying the nucleocytoplasmic shuttling of proteins can broaden our perspective and understanding

Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance

Aging and Cancer, EarlyView.
NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.
