Commun. 11:3921-3921(2020). CC -!- FUNCTION: Non-catalytic subunit of the V1 complex of vacuolar(H+)- CC ATPase (V-ATPase), a multisubunit enzyme composed of a peripheral CC complex (V1) that hydrolyzes ATP and a membrane integral complex (V0) CC that translocates protons (PubMed:32764564). V-ATPase is responsible CC for acidifying and maintaining the pH of intracellular compartments and CC in some cell types, is targeted to the plasma membrane, where it is CC responsible for acidifying the extracellular environment CC (PubMed:32764564). In renal intercalated cells, can partially CC compensate the lack of ATP6V1B1 and mediate secretion of protons (H+) CC into the urine under base-line conditions but not in conditions of acid CC load (By similarity). {ECO:0000250|UniProtKB:P62814, CC ECO:0000269|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). CC {ECO:0000269|PubMed:32764564}. CC -!- SUBCELLULAR LOCATION: Apical cell membrane CC {ECO:0000250|UniProtKB:P21281}. Melanosome CC {ECO:0000250|UniProtKB:P21281}. Cytoplasm CC {ECO:0000250|UniProtKB:P62814}. Cytoplasmic vesicle, clathrin-coated CC vesicle membrane {ECO:0000269|PubMed:32764564}; Peripheral membrane CC protein {ECO:0000305}. Cytoplasmic vesicle, secretory vesicle, synaptic CC vesicle membrane {ECO:0000250|UniProtKB:P62815}; Peripheral membrane CC protein {ECO:0000305}. CC -!- TISSUE SPECIFICITY: Expressed in brain (at protein level) CC (PubMed:1371275, PubMed:32764564). Expressed in all tissues tested, but CC highest in brain and in adrenal medulla (PubMed:1371275, CC PubMed:32764564). {ECO:0000269|PubMed:1371275, CC ECO:0000269|PubMed:32764564}. CC -!- SIMILARITY: Belongs to the ATPase alpha/beta chains family. CC {ECO:0000305}.
