Active Nuclear Import of Membrane Proteins Revisited
Cells, 2015 It is poorly understood how membrane proteins destined for the inner nuclear membrane pass the crowded environment of the Nuclear Pore Complex (NPC). For the Saccharomyces cerevisiae proteins Src1/Heh1 and Heh2, a transport mechanism was proposed where ...

eLife, 2021 Hundreds of genes interact with the yeast nuclear pore complex (NPC), localizing at the nuclear periphery and clustering with co-regulated genes. Dynamic tracking of peripheral genes shows that they cycle on and off the NPC and that interaction with the ...

Nuclear Envelope Regulation of Oncogenic Processes: Roles in Pancreatic Cancer
Epigenomes, 2018 Pancreatic cancer is an aggressive and intractable malignancy with high mortality. This is due in part to a high resistance to chemotherapeutics and radiation treatment conferred by diverse regulatory mechanisms.

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)

Plant nuclear envelope as a hub connecting genome organization with regulation of gene expression
Nucleus, 2023 Eukaryotic cells organize their genome within the nucleus with a double-layered membrane structure termed the nuclear envelope (NE) as the physical barrier.

Poring over pores: nuclear pore complex insertion into the nuclear envelope
Trends in Biochemical Sciences, 2013 The nuclear boundary is formed by the nuclear envelope (NE), a double membrane system that establishes a selective barrier between the nucleoplasm and the cytoplasm. Its barrier characteristics are determined by nuclear pore complexes (NPCs); huge protein assemblies that guard nucleocytoplasmic compartmentalization.

Puzzling out nuclear pore complex assembly
FEBS Letters, 2023 Nuclear pore complexes (NPCs) are sophisticated multiprotein assemblies embedded within the nuclear envelope and controlling the exchanges of molecules between the cytoplasm and the nucleus. In this review, we summarize the mechanisms by which these elaborate complexes are built from their subunits, the nucleoporins, based on our ever‐growing knowledge

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 ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

SARS coronavirus protein nsp1 disrupts localization of Nup93 from the nuclear pore complex.
Biochemistry and cell biology = Biochimie et biologie cellulaire, 2019 Severe acute respiratory syndrome coronavirus nonstructural protein 1 (nsp1) is a key factor in virus-induced down-regulation of host gene expression. In infected cells, nsp1 engages in a multi-pronged mechanism to inhibit host gene expression by binding
