Control of lysosomal biogenesis and Notch-dependent tissue patterning by components of the TFEB-V-ATPase axis in Drosophila melanogaster [PDF]

open access: yes, 2016
In vertebrates, TFEB (transcription factor EB) and MITF (microphthalmia-associated transcription factor) family of basic Helix-Loop-Helix (bHLH) transcription factors regulates both lysosomal function and organ development.

A thermo-physical analysis of the proton pump vacuolar-ATPase: the constructal approach [PDF]

open access: yes, 2014
Pumping protons across a membrane was a critical step at the origin of life on earth, and it is still performed in all living organisms, including in human cells. Proton pumping is paramount to keep normal cells alive, e.g.

Rag GTPases are cardioprotective by regulating lysosomal function. [PDF]

open access: yes, 2014
The Rag family proteins are Ras-like small GTPases that have a critical role in amino-acid-stimulated mTORC1 activation by recruiting mTORC1 to lysosome.

AMPK:Sensing Glucose as well as Cellular Energy Status [PDF]

open access: yes, 2018
Mammalian AMPK is known to be activated by falling cellular energy status, signaled by rising AMP/ATP and ADP/ATP ratios. We review recent information about how this occurs but also discuss new studies suggesting that AMPK is able to sense glucose ...

RAVE and Rabconnectin-3 Complexes as Signal Dependent Regulators of Organelle Acidification

open access: yesFrontiers in Cell and Developmental Biology, 2021
The yeast RAVE (Regulator of H+-ATPase of Vacuolar and Endosomal membranes) complex and Rabconnectin-3 complexes of higher eukaryotes regulate acidification of organelles such as lysosomes and endosomes by catalyzing V-ATPase assembly.

ADP Inhibition of Myosin V ATPase Activity [PDF]

open access: yesBiophysical Journal, 2000
The kinetic mechanism of myosin V is of great interest because recent evidence indicates that the two-headed myosin V molecule functions as a processive motor, i.e., myosin V is capable of moving along an actin filament for many catalytic cycles of the motor without dissociating.

Transient Receptor Potential V Channels Are Essential for Glucose Sensing by Aldolase and AMPK [PDF]

open access: yes, 2019
Fructose-1,6-bisphosphate (FBP) aldolase links sensing of declining glucose availability to AMPK activation via the lysosomal pathway. However, how aldolase transmits lack of occupancy by FBP to AMPK activation remains unclear.

Specific V-ATPase expression sub-classifies IDHwt lower-grade gliomas and impacts glioma growth in vivoResearch in context

open access: yesEBioMedicine, 2019
Background: Cancer cells use specific V-ATPase subunits to activate oncogenic pathways. Therefore, we investigated V-ATPase deregulation in aggressive gliomas and associated signaling.

The Mechanochemistry of V-ATPase Proton Pumps [PDF]

open access: yesBiophysical Journal, 2000
The vacuolar H(+)-ATPases (V-ATPases) are a universal class of proton pumps that are structurally similar to the F-ATPases. Both protein families are characterized by a membrane-bound segment (V(o), F(o)) responsible for the translocation of protons, and a soluble portion, (V(1), F(1)), which supplies the energy for translocation by hydrolyzing ATP ...

Follicular lymphoma-associated mutations in the V-ATPase chaperone Vma21 activate autophagy by dysfunctional V-ATPase assembly

open access: yesAutophagy Reports, 2022
A significant number of follicular lymphoma patients display recurrent mutations in subunits and regulators of the vacuolar-type H+-translocating ATPase (V-ATPase). Past studies focusing on the role of these mutations highlighted essential functions of macroautophagy/autophagy, amino-acid, and nutrient-sensing pathways in the pathogenesis of this ...
