CC -!- FUNCTION: Catalytic subunit of the V1 complex of vacuolar(H+)-ATPase
CC (V-ATPase), a multisubunit enzyme composed of a peripheral complex (V1)
CC that hydrolyzes ATP and a membrane integral complex (V0) that
CC translocates protons (PubMed:32764564). V-ATPase is responsible for
CC acidifying and maintaining the pH of intracellular compartments and in
CC some cell types, is targeted to the plasma membrane, where it is
CC responsible for acidifying the extracellular environment
CC (PubMed:32764564). In aerobic conditions, involved in intracellular
CC iron homeostasis, thus triggering the activity of Fe(2+) prolyl
CC hydroxylase (PHD) enzymes, and leading to HIF1A hydroxylation and
CC subsequent proteasomal degradation (By similarity). May play a role in
CC neurite development and synaptic connectivity (By similarity).
CC {ECO:0000250|UniProtKB:P38606, ECO:0000269|PubMed:32764564}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O + 4 H(+)(in) = ADP + phosphate + 5 H(+)(out);
CC Xref=Rhea:RHEA:57720, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=7.1.2.2;
CC Evidence={ECO:0000269|PubMed:32764564};
CC -!- ACTIVITY REGULATION: ATP hydrolysis occurs at the interface between the
CC nucleotide-binding domains of subunits A and B (Probable). ATP
CC hydrolysis triggers a conformational change in the subunits D and F,
CC which induces a shift of subunit d (Probable). The c-ring is
CC subsequently rotated and results in a continuous proton translocation
CC across the membrane (Probable). The V-ATPase is inhibited by
CC bafilomycin A (PubMed:32764564). {ECO:0000269|PubMed:32764564,
CC ECO:0000305|PubMed:32764564}.
CC -!- SUBUNIT: V-ATPase is a heteromultimeric enzyme made up of two
CC complexes: the ATP-hydrolytic V1 complex and the proton translocation
CC V0 complex (PubMed:32764564). The V1 complex consists of three
CC catalytic AB heterodimers that form a heterohexamer, three peripheral
CC stalks each consisting of EG heterodimers, one central rotor including
CC subunits D and F, and the regulatory subunits C and H
CC (PubMed:32764564). The proton translocation complex V0 consists of the
CC proton transport subunit a, a ring of proteolipid subunits c9c'',
CC rotary subunit d, subunits e and f, and the accessory subunits
CC ATP6AP1/Ac45 and ATP6AP2/PRR (PubMed:32764564). Interacts with the V0
CC complex V-ATPase subunit a4 ATP6V0A4 (By similarity). Interacts with
CC WFS1 (By similarity). Interacts with alpha-crystallin B chain/CRYAB and
CC with MTOR, forming a ternary complex (By similarity).

CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P38606}.

CC secretory vesicle {ECO:0000250|UniProtKB:P38606}. Cytoplasmic vesicle,
CC clathrin-coated vesicle membrane {ECO:0000269|PubMed:32764564};

CC {ECO:0000250|UniProtKB:P50516}. Note=Co-localizes with WFS1 in the
CC secretory granules in neuroblastoma cell lines.
CC {ECO:0000250|UniProtKB:P38606}.
