Store lyophilized/reconstituted 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: Arabidopsis thaliana
V-ATPase a1 (encoded by ATP6V0A1) is an integral membrane subunit of the vacuolar-type H+-ATPase (V-ATPase) that localizes predominantly to intracellular membranes, including endosomes and lysosomes, and is also enriched in neuronal compartments such as synaptic vesicles/clathrin-coated vesicles where it supports neurotransmitter loading. Structurally, V-ATPase is organized into a peripheral V1 ATP-hydrolytic sector and a membrane-embedded V0 proton-translocation sector; a1 is the V0 "a" isoform that provides a large N-terminal cytosolic domain important for V1-V0 assembly/regulation and a C-terminal multi-pass transmembrane region that interfaces with the proteolipid ring to enable proton movement across the membrane. Functionally, a1-containing V-ATPase complexes use ATP hydrolysis to pump protons into organelle lumens, generating acidity and electrochemical gradients required for protein sorting and degradation, receptor-mediated endocytosis, and vesicular trafficking, and in neurons specifically to establish the proton motive force that drives vesicular neurotransmitter uptake; consistent with this role, disease-associated ATP6V0A1 variants impair lysosomal acidification.
