A cell-based assay for CD63-containing extracellular vesicles [PDF]
Extracellular vesicles (EVs) are thought to be important in cell-cell communication and have elicited extraordinary interest as potential biomarkers of disease. However, quantitative methods to enable elucidation of mechanisms underlying release are few.

Retrieval of the vacuolar H-ATPase from phagosomes revealed by live cell imaging. [PDF]
BackgroundThe vacuolar H+-ATPase, or V-ATPase, is a highly-conserved multi-subunit enzyme that transports protons across membranes at the expense of ATP.

Rapid purification of human lysosomal membranes, characterisation of the detergent resistent microdomains, purification and reconstitution of the vacuolar proton pump (V-ATPase) [PDF]
The lysosomal membrane is a dynamic environment where specific interactions among proteins and between proteins and lipids occur. These interactions are necessary for the proper functioning of the lysosomal apparatus that allows the passage of molecules ...

V-ATPase engagement in autophagic processes [PDF]
The proton pumping activity of V-ATPase is responsible for acidification of the lysosome/vacuole. The low lumenal pH of this organelle stimulates the activity of a battery of resident hydrolases responsible for the degradation of various nonselective and selective cargos delivered by autophagic processes.

F-actin reorganization by V-ATPase inhibition in prostate cancer
The vacuolar ATPase (V-ATPase) proton pump sustains cellular pH homeostasis, and its inhibition triggers numerous stress responses. However, the cellular mechanisms involved remain largely elusive in cancer cells.

Saccharomyces cerevisiae mutants affected in vacuole assembly or vacuolar H+-ATPase are hypersensitive to lead (Pb) toxicity [PDF]
Lead is an important environmental pollutant. The role of vacuole, in Pb detoxification, was studied using a vacuolar protein sorting mutant strain (vps16Δ), belonging to class C mutants.

The curious case of vacuolar ATPase: regulation of signaling pathways
The Vacuolar ATPase (V-ATPase) is a proton pump responsible for controlling the intracellular and extracellular pH of cells. The structure of V-ATPase has been highly conserved among all eukaryotic cells and is involved in diverse functions across ...

The E3 ubiquitin ligase ZNRF2 is a substrate of mTORC1 and regulates its activation by amino acids [PDF]
The mechanistic Target of Rapamycin complex 1 (mTORC1) senses intracellular amino acid levels through an intricate machinery, which includes the Rag GTPases, Ragulator and vacuolar ATPase (V-ATPase).

mTORC1 Senses Lysosomal Amino Acids Through an Inside-Out Mechanism That Requires the Vacuolar H+-ATPase [PDF]
The mTOR complex 1 (mTORC1) protein kinase is a master growth regulator that is stimulated by amino acids. Amino acids activate the Rag guanosine triphosphatases (GTPases), which promote the translocation of mTORC1 to the lysosomal surface, the site of ...
