A dominant negative mitofusin causes mitochondrial perinuclear clusters because of aberrant tethering

open access: yesLife Science Alliance, 2023
Our analysis of a CMT2A-associated mitofusin variant reveals that aberrant mitochondrial tethering results in perinuclear clusters and that conformational dynamics in Hinge 2 are required to progress from membrane tethering to membrane fusion.

Secretory Vesicles Targeted to Plasma Membrane During Pollen Germination and Tube Growth

open access: yesFrontiers in Cell and Developmental Biology, 2021
Pollen germination and pollen tube growth are important biological events in the sexual reproduction of higher plants, during which a large number of vesicle trafficking and membrane fusion events occur.

Docking and stability defects in mitofusin highlight the proteasome as a potential therapeutic target

open access: yesiScience, 2023
Summary: Defects in mitochondrial fusion are at the base of many diseases. Mitofusins power membrane-remodeling events via self-interaction and GTP hydrolysis.

The Molecular Determinants of Mitochondrial Membrane Contact With ER, Lysosomes and Peroxisomes in Neuronal Physiology and Pathology

open access: yesFrontiers in Cellular Neuroscience, 2020
Membrane tethering is an important communication method for membrane-packaged organelles. Mitochondria are organelles with a bilayer membrane, and the membrane contact between mitochondria and other organelles is indispensable for maintaining cellular ...

Membrane-anchored human Rab GTPases directly mediate membrane tethering in vitro

open access: yesBiology Open, 2014
Rab GTPases are master regulators of eukaryotic endomembrane systems, particularly functioning in membrane tethering to confer the directionality of intracellular membrane trafficking.

Loosening ER–Mitochondria Coupling by the Expression of the Presenilin 2 Loop Domain

open access: yesCells, 2021
Presenilin 2 (PS2), one of the three proteins in which mutations are linked to familial Alzheimer’s disease (FAD), exerts different functions within the cell independently of being part of the γ-secretase complex, thus unrelated to toxic amyloid peptide ...

Structure of the HOPS tethering complex, a lysosomal membrane fusion machinery

open access: yeseLife, 2022
Lysosomes are essential for cellular recycling, nutrient signaling, autophagy, and pathogenic bacteria and viruses invasion. Lysosomal fusion is fundamental to cell survival and requires HOPS, a conserved heterohexameric tethering complex.

Tethering complexes in the Arabidopsis endomembrane system

open access: yesFrontiers in Cell and Developmental Biology, 2016
Targeting of endomembrane transport containers is of the utmost importance for proper land plant growth and development. Given the immobility of plant cells, localized membrane vesicle secretion and recycling are amongst the main processes guiding proper
