Summary: The short amphipathic alpha-helix of Apq12 regulates the function of Brl1 and Brr6, leading to defects in NPC biogenesis and NE integrity when disrupted. Overexpression of Apq12 promotes over-proliferation of the ONM/ER and accumulation of phosphatidic acid at the NE, possibly during NPC biogenesis.

Summary: The nuclear pore complexes (NPCs) in eukaryotic cells are responsible for macromolecular transport in and out of the nucleus. The NPCs contain intrinsically disordered proteins (IDPs) and efficiently transport cargoes in crowded conditions. A computational model of the NPC shows that self-regulating mechanisms and the spatial architecture of the IDP assembly contribute to efficient transport.

Summary: This study revealed that the phase separation of the nuclear pore complex (NPC) central barrier plays a crucial role in regulating plant defense against various biotic stresses. The NUP62 gene was found to positively regulate plant defense against the plant pathogen Botrytis cinerea. Further investigation showed that the phase separation of the NPC central barrier regulates the nucleocytoplasmic transport of immune regulators and activates plant defense against a broad range of biotic stresses.

Summary: The nuclear pore complex (NPC) is a large protein complex in eukaryotes that regulates the transport of molecules between the nucleus and cytoplasm. By using cryo-electron microscopy and AlphaFold2, researchers determined the structure of the outer rings of the Xenopus laevis NPC and identified the composition and interactions of its components. This detailed structural information represents a significant advancement in understanding the assembly of the NPC.

Summary: A synthetic hydrogel platform was developed to analyze the molecular interaction between toxic arginine-rich DPRs and the nuclear pore complex, providing evidence that these DPRs target NPC and block selective entry of key nuclear transport receptors. The ease of adjustment of these synthetic hydrogel mimics makes them a valuable tool for dissecting complex molecular interactions underlying cellular transport processes and disease perturbations.

Summary: The NPC is a proteinaceous nanopore that mediates molecular transport between the nucleus and cytoplasm in eukaryotic cells, regulating gene expression. Our research highlights the importance of chemistry in understanding and controlling NPC-mediated molecular transport for efficient genetic therapeutics delivery into the nucleus, contributing to human health. We use nanoscale scanning electrochemical microscopy to study how the NPC nanopore is divided into peripheral and central routes to facilitate protein transport and RNA export through hydrophobic and electrostatic interactions.

Summary: Nup214 is a major nucleoporin involved in nuclear protein and mRNA export processes, interacting with the export receptor CRM1 via specific FG repeats and a classic NES. Mutations in the NES of Nup214 lead to nuclear accumulation, suggesting a role in NPC biogenesis and CRM1-dependent protein export terminal steps. The rescue of mutant Nup214 nuclear export with artificial NES indicates a potential mechanism for correct localization of Nup88.

Summary: The nuclear pore complex (NPC) is a platform for studying the evolution of early-branching eukaryotes, but the Plasmodium NPC is poorly defined due to its evolutionary divergence. In this study, a labeling methodology based on TurboID fusion proteins was developed to visualize and identify the components of the Plasmodium NPC. Through affinity purification and mass spectrometry, several known nucleoporins (Nups) and previously unannotated proteins were identified as components of the NPC. These findings contribute to a better understanding of the function and evolutionary position of the Plasmodium NPC.

Summary: Various viruses manipulate the integrity of the nuclear pore complex (NPC) to facilitate their replication by altering nucleus-cytoplasmic transport. This alteration is not only observed in viruses with nuclear replicative cycles, but also in viruses with cytoplasmic replication. Viral proteins, particularly viral proteases, play a crucial role in mediating these changes.

Summary: Although the nuclear envelope separates the nucleus and cytoplasm in eukaryotes, a semipermeable barrier is necessary to allow material exchange between these compartments. This barrier is achieved through nuclear pores, which facilitate the active transport of macromolecules. The diffusion of macromolecules through these pores is impeded by a dense network of unfolded regions of nucleoporins. Additional mechanisms, such as binding to immobile components and active removal, are required to maintain the distinctive compositions of each compartment.

Summary: Dictyostelium cells undergo a semi-closed mitosis, during which the nuclear envelope persists but free diffusion occurs between the cytoplasm and nucleus. Partial disassembly of the nuclear pore complexes allows for permeabilization of the nuclear envelope and facilitates the formation of the mitotic spindle.

Summary: This study explores the importance of nuclear positioning in cell differentiation, division, and movement, as well as the mechanism by which forces are transmitted through the LINC complex on both sides of the nuclear membrane. The binding structure of Nes2G to FHOD1 suggests that the SR binding by FHOD1 may not be regulated by its own structure. Additionally, it was found that Nes1G also binds to FHOD1, indicating potential overlapping functions of these giant Nesprins in recruiting actin bundles for nuclear movement.

Summary: Misuse of antibiotics in aquaculture poses a public health risk and leads to the emergence of multiresistant pathogens. Rapid test kits are used to monitor food supply chains but lack accuracy. Researchers have developed single-domain antibodies that can improve the reliability and shelf-life of these test kits for small molecule antibiotics.
