Nucleoporins facilitate ORC loading onto chromatin
SUMMARYThe origin recognition complex (ORC) binds throughout the genome to initiate DNA replication. In metazoans, it is still unclear how ORC is targeted to specific loci to facilitate helicase loading and replication initiation. Here, we performed immunoprecipitations coupled with mass spectrometry for ORC2 in Drosophila embryos.

Phase Separation Regulates Metabolism, Mitochondria, and Diseases
Mitochondrion‐related liquid–liquid phase separation. (1) Phase separation mediates the self‐assembly of mitochondrial nucleoids (mt‐nucleoids). (2) Phase segregation mediates the formation of mitochondrial RNA granules (MRGs). (3) Phase separation mediates the formation of mitochondrial degradosomes.

Cytoplasmic nucleoporin assemblage: the cellular artwork in physiology and disease
Nucleoporins, essential proteins building the nuclear pore, are pivotal for ensuring nucleocytoplasmic transport. While traditionally confined to the nuclear envelope, emerging evidence indicates their presence in various cytoplasmic structures ...

Nucleoporin-mediated regulation of cell identity genes [PDF]
The organization of the genome in the three-dimensional space of the nucleus is coupled with cell type-specific gene expression. However, how nuclear architecture influences transcription that governs cell identity remains unknown. Here, we show that nuclear pore complex (NPC) components Nup93 and Nup153 bind superenhancers (SE), regulatory structures ...

The silencing of transposable elements is mediated by piRNAs through post‐transcriptional and transcriptional regulation. In Drosophila, piRNAs are processed within unique non‐membrane structures: nuage in germline cells and Yb bodies in somatic gonadal cells.

Importin 7 and Nup358 promote nuclear import of the protein component of human telomerase.
In actively dividing eukaryotic cells, chromosome ends (telomeres) are subject to progressive shortening, unless they are maintained by the action of telomerase, a dedicated enzyme that adds DNA sequence repeats to chromosomal 3'end.

MINFLUX Nanoscopy: A “Brilliant” Technique Promising Major Breakthrough
Minflux localization microscopy technique allows for both nm‐scale resolution in imaging and up to 10 kHz speed in tracking of single molecules. ABSTRACT MINFLUX nanoscopy relies on the localization of single fluorophores with expected ~ 2 nm precision in 3D mapping, roughly one order of magnitude better than standard stimulated emission depletion ...

Nucleoporin Gene Fusions and Hematopoietic Malignancies [PDF]
Nuclear pore complexes (NPCs) are the sole gateways between the nucleus and the cytoplasm of eukaryotic cells and they mediate all macromolecular trafficking between these cellular compartments. Nucleocytoplasmic transport is highly selective and precisely regulated and as such an important aspect of normal cellular function. Defects in this process or

A SUMO-dependent feedback loop senses and controls the biogenesis of nuclear pore subunits
The nuclear pore complex is crucial for mediating nucleocytoplasmic exchanges. Here the authors use budding yeast to reveal a mechanism responsible of maintaining nucleoporin homeostasis by sensing changes in the complex integrity and further altering ...
