The plasma membrane V-ATPase of Manduca sexta larval midgut is an electrogenic proton pump located in goblet cell apical membranes (GCAM); it energizes, by the voltage component of its proton motive force, an electrophoretic K/nH antiport and thus K secretion (Wieczorek, H., Putzenlechner, M., Zeiske, W., and Klein, U.(1991) J. Biol Chem. 266, 15340-15347). Midgut transepithelial voltage, indicating net active K transport, was found to be more than 100 mV during intermoult stages but was… 
cAMP regulates plasma membrane vacuolar-type H+-ATPase assembly and activity in blowfly salivary glands.
TLDR
These findings suggest that the cAMP pathway mediates the reversible assembly and activation of V-ATPase molecules at the apical membrane upon hormonal stimulus.
The Insect Plasma Membrane H+ V-ATPase: Intra-, Inter-, and Supramolecular Aspects
The plasma membrane H+ V-ATPase from the midgut of larval Manduca sexta, commonly called the tobacco hornworm, is the sole energizer of epithelial ion transport in this tissue, being responsible for
Regulation of V-ATPase activity.
TLDR
V-ATPases are ATP-driven proton pumps present in both intracellular and cell surface membranes of eukaryotes that function in many normal and disease processes and differential expression of genes encoding V- ATPases subunits occurs in a number of contexts, including cancer.
Structure and Regulation of the V-ATPases
TLDR
The role that intracellular environment, luminal pH and a unique domain of the catalytic A subunit play in controlling reversible dissociation in vivo is investigated.
Structure, function and regulation of the vacuolar (H+)-ATPase.
TLDR
Several mechanisms have been implicated in the regulation of vacuolar acidification in vivo, including control of pump density, regulation of assembly of V1 and V0 domains, disulfide bond formation, activator or inhibitor proteins, and regulation of counterion conductance.
The vacuolar-type H+-ATPase at a glance – more than a proton pump
TLDR
These non-canonical functions of the V-ATPase, which include fusogenicity, cytoskeletal tethering and metabolic sensing, are described in this Cell Science at a Glance article and accompanying poster.
STRUCTURE, FUNCTION AND REGULATION OF THE VACUOLAR
TLDR
Several mechanisms have been implicated in the regulation of vacuolar acidification in vivo, including control of pump density, regulation of assembly of V1 and V0 domains, disulfide bond formation, activator or inhibitor proteins, and regulation of counterion conductance.
A Novel Role for Subunit C in Mediating Binding of the H+-V-ATPase to the Actin Cytoskeleton*
TLDR
Overlay blots and co-pelleting assays showed that the recombinant subunit C also binds to F-actin, which may function as an anchor protein regulating the linkage between V-ATPase and the actin-based cytoskeleton.
Characterisation of the human H⁺-ATPase a4 subunit.
TLDR
Findings indicate a direct link between V-ATPase and glycolysis, via the C-terminus of the pump's a subunit, and suggest a novel regulatory mechanismBetween V- ATPase function and energy supply.

The insect V-ATPase, a plasma membrane proton pump energizing secondary active transport: molecular analysis of electrogenic potassium transport in the tobacco hornworm midgut.
TLDR
The midgut provides an alternative to the classical concept of animal plasma membrane energization by the Na(+)-motive force generated by theNa+/K(+-ATPase, as well as a high degree of identity to the sequences of the respective subunits of other V- ATPases.
Biochemistry of the renal V-ATPase.
TLDR
Recent experiments have begun to reveal how the kidney controls transcellular proton transport while still maintaining acidification of intracellular compartments, including V-ATPases in selective membrane compartments.

TLDR
Two approaches provide complementary frameworks for understanding how the compartment receiving protons from a V-ATPase can be rendered acidic, neutral or even alkaline, depending upon the selectivity of other carriers (porters) and channels present, upon the strength of the gegenions and upon the cellular and compartmental geometry.
Assembly of the peripheral domain of the bovine vacuolar H+‐adenosine triphosphatase
TLDR
The biosynthesis and assembly of the peripheral sector (V1) of the vacuolar protontranslocating adenosine triphosphatase (V‐ATPase) was studied in a bovine kidney epithelial cell line and suggested that assembly of V1V0 is probably completed in the endoplasmic reticulum prior to distribution of the enzyme throughout the cell.

TLDR
The hypothesis that a vacuolar-type H + -ATPase provides an alternative to the Na + /K + - ATPase in energizing animal plasma membranes in energization of insect plasma membranes is supported.
