The scaffold nucleoporins SAR1 and SAR3 are essential for proper meiotic progression in Arabidopsis thaliana

, 2023
Nuclear Pore Complexes (NPCs) are embedded in the nuclear envelope (NE), regulating macromolecule transport and physically interacting with chromatin. The NE undergoes dramatic breakdown and reformation during plant cell division.

Cytoplasmic nucleoporin assemblage: the cellular artwork in physiology and disease

Nucleus
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 ...

Identification of Yeast Protein Sequences With Similarity to the ESCRT‐III Protein Snf7

Yeast, EarlyView.
ABSTRACT Endosomal sorting complex required for transport (ESCRT‐III) is a membrane remodeling complex involved in a large number of cellular processes. It appears to perform an essential function in eukaryotes, since to date no eukaryotic organism completely devoid of ESCRT‐III has been found.

Functional insights of nucleocytoplasmic transport in plants

Frontiers in Plant Science, 2014
Plant nucleocytoplasmic transport beyond the nuclear envelope is important not only for basic cellular functions but also for growth, development, hormonal signalling, and responses to environmental stimuli.

Selective autophagy pathways in ageing and neurodegeneration: Emerging roles for mitophagy and nucleophagy

The FEBS Journal, EarlyView.
As we age, cells gradually accumulate damage, which can contribute to disease and neurodegeneration. This review explores how two cellular recycling processes, mitophagy and nucleophagy, remove damaged mitochondria and nuclear material, respectively, to maintain cell health and long‐term neuronal homeostasis.

Two structurally distinct domains of the nucleoporin Nup170 cooperate to tether a subset of nucleoporins to nuclear pores [PDF]

Journal of Cell Biology, 2009
How individual nucleoporins (Nups) perform their role in nuclear pore structure and function is largely unknown. In this study, we examined the structure of purified Nup170 to obtain clues about its function. We show that Nup170 adopts a crescent moon shape with two structurally distinct and separable domains, a β-propeller N terminus and an α-solenoid

The Cytosolic Iron–Sulfur Cluster Assembly Targeting Complex Is Hijacked by Magnaporthe Effector AvrPi9 to Suppress Rice Resistance

Plant Biotechnology Journal, EarlyView.
ABSTRACT The cytosolic iron–sulfur (Fe‐S) cluster assembly (CIA) targeting complex mediates the maturation of cytosolic and nuclear Fe‐S proteins and governs core eukaryotic cellular processes. However, whether this complex contributes to plant disease resistance remains unclear.

Co-translational assembly orchestrates competing biogenesis pathways

Nature Communications, 2022
The biogenesis of nuclear pores imposes a logistic challenge for cells. Here, the authors investigate structural motifs for co-translational interactions in nucleoporins and find that co-translational assembly events differ between paralogous assembly ...

Photoperiodism‐Specific QTLs Support Switch‐Like Genetic Control of Obligate Long‐Day Photoperiodism in Mimulus guttatus

Plant Species Biology, Volume 41, Issue 6, November 2026.
Photoperiodic flowering is well studied in facultative photoperiodism plants, but the genetic basis of obligate photoperiodism remains poorly understood. Using QTL mapping and RNA‐seq in Mimulus guttatus, we identified photoperiodism‐specific QTLs that are distinct from flowering‐time QTLs, supporting switch‐like genetic control of obligate long‐day ...

The Multiple Faces of Disordered Nucleoporins

Journal of Molecular Biology, 2016
An evolutionary advantage of intrinsically disordered proteins (IDPs) is their ability to bind a variety of folded proteins-a paradigm that is central to the nucleocytoplasmic transport mechanism, in which nuclear transport receptors mediate the translocation of various cargo through the nuclear pore complex by binding disordered phenylalanine-glycine ...
