Store at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
For reconstitution add 50 µL of sterile water.
Specific Species Reactivity: Avena sativa
V-ATPase is a conserved, multi-subunit rotary proton pump that localizes primarily to endomembrane compartments (including endosomes, lysosomes, secretory vesicles, and the Golgi network) and, in specialized cells, is also targeted to the plasma membrane to acidify the extracellular space. It is organized into two coupled sectors: a peripheral, cytosolic V1 domain that catalyzes ATP hydrolysis and a membrane-embedded V0 domain that translocates protons across the membrane; the V1 domain contains a catalytic A3B3 head with additional stalk/regulatory subunits (including C, D, E, F, G, and H) that couple nucleotide turnover to rotation, while the V0 domain comprises the large a subunit and a proteolipid c-ring with additional subunits (including d and e) that form the proton-conducting pathway. By pumping H+ into organelle lumens, V-ATPase establishes the acidic pH and electrochemical gradients required for receptor-mediated endocytosis, protein sorting and trafficking, activation of acid-dependent hydrolases/zymogens, and loading of neurotransmitters into synaptic vesicles; isoform-specific subunit usage contributes to compartment- and cell-type-specific targeting and functions, including osteoclast-mediated acidification at the bone-apposed membrane and regulation of lysosomal acidification linked to neurodegenerative and storage disease phenotypes.
