Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

open access: yesFEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Importance of Endocytosis for the Biological Activity of Cedar Virus Fusion Protein

open access: yesCells, 2020
Endocytosis plays a particular role in the proteolytic activation of highly pathogenic henipaviruses Hendra (HeV) and Nipah virus (NiV) fusion (F) protein precursors. These proteins require endocytic uptake from the cell surface to be cleaved by cellular

Suppression of lung adenocarcinoma migration through organelle alkalization by human lactoferrin – albumin fusion

open access: yesFEBS Open Bio, EarlyView.
This paper reveals how human lactoferrin–albumin fusion (hLF‐HSA) potently suppresses lung adenocarcinoma cell migration. hLF‐HSA upregulates NHE7, leading to Golgi alkalization, disruption of the Golgi secretome, downregulation of MMP1, and reversal of EMT. These findings suggest a novel Golgi‐targeting strategy to suppress cancer cell migration.

SNX9 family mediates βarrestin-independent GPCR endocytosis

open access: yesCommunications Biology
Agonist-stimulated GPCR endocytosis typically occurs via the multi-faceted adaptor proteins known as βarrestins. However, endocytosis of several GPCRs occurs independently of β-arrestins, suggesting an additional mode of GPCR endocytosis, but the ...

Single Event Resolution of Plant Plasma Membrane Protein Endocytosis by TIRF Microscopy

open access: yesFrontiers in Plant Science, 2017
Endocytosis is a key process in the internalization of extracellular materials and plasma membrane proteins, such as receptors and transporters, thereby controlling many aspects of cell signaling and cellular homeostasis.

Myosin VIIA is required for aminoglycoside accumulation in cochlear hair cells. [PDF]

open access: yes, 1997
Myosin VIIA is expressed by sensory hair cells and has a primary structure predicting a role in membrane trafficking and turnover, processes that may underlie the susceptibility of hair cells to aminoglycoside antibiotics. [3H]Gentamicin accumulation and

Ligand-induced monoubiquitination of BIK1 regulates plant immunity [PDF]

open access: yes, 2020
The detection of microorganism-associated ligands by plant cells activates a signalling cascade in which the kinase BIK1 is monoubiquinated, released from the FLS2-BAK1 complex, and internalized by endocytosis. Recognition of microbe-associated molecular

Lipopolysaccharide uptake is augmented in lipopolysaccharide‐tolerant mouse macrophage‐like cells via increased CD14 expression

open access: yesFEBS Open Bio, EarlyView.
In normal (nontolerant) cells, CD14 is crucial for both LPS uptake and LPS signaling. In LPS‐tolerant cells, in which LPS‐induced TNF‐α and IFN‐β production is suppressed, there is a dramatic increase in surface CD14 expression. The overexpressed CD14 in LPS‐tolerant cells is responsible for the enhanced LPS uptake without inducing pro‐inflammatory ...

IRR is involved in glucose-induced endocytosis after insulin secretion

open access: yesJournal of Pharmacological Sciences, 2019
Endocytosis after insulin secretion plays a pivotal role in the regulation of insulin secretion in pancreatic β-cells. Our recent study suggested that EPI64, a GTPase activating protein for Rab27a, contributes to the regulation of glucose-induced ...

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

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