DNA origami scaffold for studying intrinsically disordered proteins of the nuclear pore complex
Nature Communications, 2018 FG-Nups are disordered proteins in the nuclear pore complex (NPC) where they selectively control nuclear transport. Here authors build NPC-mimics based on DNA origami rings which attach a certain numbers of Nups to analyse those nanopores by cryoEM and ...

Nuclear envelope budding and its cellular functions
Nucleus, 2023 The nuclear pore complex (NPC) has long been assumed to be the sole route across the nuclear envelope, and under normal homeostatic conditions it is indeed the main mechanism of nucleo-cytoplasmic transport.

Higher nucleoporin-Importinβ affinity at the nuclear basket increases nucleocytoplasmic import.
PLoS ONE, 2013 Several in vitro studies have shown the presence of an affinity gradient in nuclear pore complex proteins for the import receptor Importinβ, at least partially contributing to nucleocytoplasmic transport, while others have historically argued against the

hnRNPA3 regulates hESCs pluripotency through modulating mRNA export [PDF]
Jichu yixue yu linchuang, 2021 Objective To explore the biological function of RNA binding protein heterogeneous nuclear ribonucleoprotein A3(hnRNPA3) in the maintenance of pluripotency of human embryonic stem cells(hESCs) and to reveal its new mechanism in RNA transport.

Progress in the study of parvovirus entry pathway
Virology Journal, 2023 A group of DNA viruses called parvoviruses that have significant effects on cancer therapy and genetic engineering applications. After passing through the cell membrane to reach the cytosol, it moves along the microtubule toward the nuclear membrane. The

Protein sub-nuclear localization prediction using SVM and Pfam domain information. [PDF]
PLoS ONE, 2014 The nucleus is the largest and the highly organized organelle of eukaryotic cells. Within nucleus exist a number of pseudo-compartments, which are not separated by any membrane, yet each of them contains only a specific set of proteins.

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Hop-on hop-off: importin-a-guided tours to the nucleus in innate immune signaling
Frontiers in Plant Science, 2013 Nuclear translocation of immune regulatory proteins and signal transducers is an essential process in animal and plant defense signaling against pathogenic microbes.

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

PLoS BiologyNuclear export of mRNAs requires loading the mRNP to the transporter Mex67/Mtr2 in the nucleoplasm, controlled access to the pore by the basket-localised TREX-2 complex and mRNA release at the cytoplasmic site by the DEAD-box RNA helicase Dbp5 ...
