Energy and Dynamics of Caveolae Trafficking

open access: yesFrontiers in Cell and Developmental Biology, 2021
Caveolae are 70–100 nm diameter plasma membrane invaginations found in abundance in adipocytes, endothelial cells, myocytes, and fibroblasts. Their bulb-shaped membrane domain is characterized and formed by specific lipid binding proteins including ...

Structural analysis of a trimeric assembly of the mitochondrial dynamin-like GTPase Mgm1. [PDF]

open access: yes, 2020
The fusion of inner mitochondrial membranes requires dynamin-like GTPases, Mgm1 in yeast and OPA1 in mammals, but how they mediate membrane fusion is poorly understood.

OPA1 disease alleles causing dominant optic atrophy have defects in cardiolipin-stimulated GTP hydrolysis and membrane tubulation [PDF]

open access: yes, 2010
The dynamin-related GTPase OPA1 is mutated in autosomal dominant optic atrophy (DOA) (Kjer type), an inherited neuropathy of the retinal ganglion cells.

Syntaphilin Binds to Dynamin-1 and Inhibits Dynamin-dependent Endocytosis [PDF]

open access: yesJournal of Biological Chemistry, 2003
Syntaphilin is a brain-specific syntaxin-binding partner first characterized as an inhibitor of SNARE complex formation and neurotransmitter release. Here we show that syntaphilin also binds to dynamin-1 and through this interaction inhibits dynamin-mediated endocytosis. Immunoprecipitation studies from cross-linked rat synaptosomes demonstrate that an

Targeting Dynamin 2 as a Novel Pathway to Inhibit Cardiomyocyte Apoptosis Following Oxidative Stress

open access: yesCellular Physiology and Biochemistry, 2016

Emerging functions of mammalian mitochondrial fusion and fission [PDF]

open access: yes, 2005
Mitochondria provide a myriad of services to the cell, including energy production, calcium buffering and regulation of apoptosis. How these diverse functions are coordinated among the hundreds of mitochondria in a given cell is largely unknown, but is ...

Membrane fission by dynamin: what we know and what we need to know [PDF]

open access: yes, 2016
The large GTPase dynamin is the first protein shown to catalyze membrane fission. Dynamin and its related proteins are essential to many cell functions, from endocytosis to organelle division and fusion, and it plays a critical role in many physiological

Structural inhibition of dynamin-mediated membrane fission by endophilin

open access: yeseLife, 2017
Dynamin, which mediates membrane fission during endocytosis, binds endophilin and other members of the Bin-Amphiphysin-Rvs (BAR) protein family. How endophilin influences endocytic membrane fission is still unclear.

Mechanistic-Based Classification of Endocytosis-Related Inhibitors: Does It Aid in Assigning Drugs against SARS-CoV-2?

open access: yesViruses, 2023
Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) canonically utilizes clathrin-mediated endocytosis (CME) and several other endocytic mechanisms to invade airway epithelial cells. Endocytic inhibitors, particularly those targeting CME-related

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

open access: yesMolecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.
