Mutations in human dynamin block an intermediate stage in coated vesicle formation [PDF]

, 1993
The role of human dynamin in receptor-mediated endocytosis was investigated by transient expression of GTP-binding domain mutants in mammalian cells. Using assays which detect intermediates in coated vesicle formation, the dynamin mutants were found to ...

AP-3 adaptor complex-mediated vesicle trafficking

Biophysics Reports, 2021
The transport of cargo proteins to specific subcellular destinations is crucial for the different secretory and endocytic traffic pathways. One of the most important steps in maintaining the accuracy of this process is the recruitment of adaptor protein (AP) complexes to the membrane for recognizing and packaging cargo proteins into nascent vesicles ...

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Molecular mechanisms of Sar/Arf GTPases in vesicular trafficking in yeast and plants

Frontiers in Plant Science, 2014
Small GTPase proteins play essential roles in the regulation of vesicular trafficking systems in eukaryotic cells. Two types of small GTPases, secretion-associated Ras-related protein (Sar) and ADP-ribosylation factor (Arf), act in the biogenesis of ...

Golgi-associated Rab GTPases implicated in autophagy

Cell & Bioscience, 2021
Autophagy is a conserved cellular degradation process in eukaryotes that facilitates the recycling and reutilization of damaged organelles and compartments.

Recently recycled synaptic vesicles use multi-cytoskeletal transport and differential presynaptic capture probability to establish a retrograde net flux during ISVE in central neurons

Frontiers in Cell and Developmental Biology, 2023
Presynapses locally recycle synaptic vesicles to efficiently communicate information. During use and recycling, proteins on the surface of synaptic vesicles break down and become less efficient.

Axonal amyloid precursor protein and its fragments undergo somatodendritic endocytosis and processing. [PDF]

, 2015
Deposition of potentially neurotoxic Aβ fragments derived from amyloid precursor protein (APP) at synapses may be a key contributor to Alzheimer's disease.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Endomembrane trafficking driven by microtubule growth regulates stomatal movement in Arabidopsis

Nature Communications
Microtubule-based vesicle trafficking usually relies upon kinesin and dynein motors and few reports describe microtubule polymerisation driving directional vesicle trafficking.

Sec6 mutations and the Drosophila exocyst complex [PDF]

, 2005
To allow a detailed analysis of exocyst function in multicellular organisms, we have generated sec6 mutants in Drosophila. We have used these mutations to compare the phenotypes of sec6 and sec5 in the ovary and nervous system, and we find them to be ...
