SH3 Domains Differentially Stimulate Distinct Dynamin I Assembly Modes and G Domain Activity.

PLoS ONE, 2015
Dynamin I is a highly regulated GTPase enzyme enriched in nerve terminals which mediates vesicle fission during synaptic vesicle endocytosis. One regulatory mechanism involves its interactions with proteins containing Src homology 3 (SH3) domains.

Functional interaction of Parkinson's disease-associated LRRK2 with members of the dynamin GTPase superfamily [PDF]

, 2017
Mutations in LRRK2 cause autosomal dominant Parkinson's disease (PD). LRRK2 encodes a multi-domain protein containing GTPase and kinase domains, and putative protein-protein interaction domains.

Reduced Oligodendrocyte Density and Axonal Caliber Associated With Mitochondrial Alterations in the White Matter of Chronically‐Starved Mice

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Anorexia nervosa (AN) is a severe eating disorder associated with extreme weight loss, hyperactivity, and amenorrhea. Neuroimaging studies revealed brain atrophy and disruption of white matter integrity in the corpus callosum (CC) of patients with AN. However, the underlying pathophysiological mechanisms remain unclear.

Cell entry of bovine respiratory syncytial virus through clathrin-mediated endocytosis is regulated by PI3K-Akt and Src-JNK pathways

Frontiers in Microbiology
Bovine respiratory syncytial virus (BRSV) is an RNA virus with envelope that causes acute, febrile, and highly infectious respiratory diseases in cattle. However, the manner and mechanism of BRSV entry into cells remain unclear.

A Dynamin Mutant Defines a Superconstricted Prefission State

Cell Reports, 2014
Dynamin is a 100 kDa GTPase that organizes into helical assemblies at the base of nascent clathrin-coated vesicles. Formation of these oligomers stimulates the intrinsic GTPase activity of dynamin, which is necessary for efficient membrane fission during

The Metabolic Role of Mitochondria in the Perinatal Cardiac Development and Cardiovascular Diseases

Exploration, EarlyView.
This review explores the critical role of mitochondria in heart development and cardiovascular disease. It highlights how mitochondrial maturation during embryonic‐to‐postnatal transition, regulated by oxygen and metabolic changes, shapes cardiac structure and function.

A feedback loop between dynamin and actin recruitment during clathrin-mediated endocytosis.

PLoS Biology, 2012
Clathrin-mediated endocytosis proceeds by a sequential series of reactions catalyzed by discrete sets of protein machinery. The final reaction in clathrin-mediated endocytosis is membrane scission, which is mediated by the large guanosine triophosphate ...

Interkingdom Interactions in the Gut: Ecological Mechanisms, Homeostasis, and Therapeutic Modulation

Gut Medicine, EarlyView.
ABSTRACT The gut microbiota constitutes a highly complex and dynamic ecosystem that profoundly influences host physiology, metabolism, and immunity. This review provides an integrative overview of the mechanisms through which gut microorganisms—particularly bacteria and fungi—interact with host cells and with each other to maintain intestinal ...

Hyperoxia Causes Mitochondrial Fragmentation in Pulmonary Endothelial Cells by Increasing Expression of Pro-Fission Proteins [PDF]

, 2018
Objective—We explored mechanisms that alter mitochondrial structure and function in pulmonary endothelial cells (PEC) function after hyperoxia. Approach and Results—Mitochondrial structures of PECs exposed to hyperoxia or normoxia were visualized and ...

Dynamin-mediated membrane fission

, 2012
La cellule eukaryote est organisée en plusieurs compartiments, appelés organelles, délimités par des membranes. La fission des membranes est nécessaire pour le transport intracellulaire entre organelles. L'endocytose est un mécanisme de transport depuis la membrane plasmique vers les autres organelles.
