Vacuolar ATPase is responsible for acidifying a variety of intracellular compartments in eukaryotic cells, thus providing most of the energy required for transport processes in the vacuolar system.[PIRNR:PIRNR018497] [VPP1_RAT] Required for assembly and activity of the vacuolar ATPase. Potential role in differential targeting and regulation of the enzyme for a specific organelle (By similarity). [VA0E2_RAT] Vacuolar ATPase is responsible for acidifying a variety of intracellular compartments in eukaryotic cells. [VATL_RAT] Proton-conducting pore forming subunit of the membrane integral V0 complex of vacuolar ATPase. V-ATPase is responsible for acidifying a variety of intracellular compartments in eukaryotic cells (By similarity). [VATF_RAT] Subunit of the peripheral V1 complex of vacuolar ATPase essential for assembly or catalytic function. V-ATPase is responsible for acidifying a variety of intracellular compartments in eukaryotic cells. [RENR_RAT] Multifunctional protein which functions as a renin, prorenin cellular receptor and is involved in the assembly of the proton-transporting vacuolar (V)-ATPase protein pump. May mediate renin-dependent cellular responses by activating ERK1 and ERK2. By increasing the catalytic efficiency of renin in AGT/angiotensinogen conversion to angiotensin I, it may also play a role in the renin-angiotensin system (RAS) (By similarity). Probably by controlling the assembly of the V-ATPase pump and thus the acidification of the endo-lysosomal system, plays a role in many neuronal processes including synapse morphology and synaptic transmission (By similarity).[UniProtKB:O75787][UniProtKB:Q9CYN9] [VAS1_RAT] Accessory subunit of the proton-transporting vacuolar (V)-ATPase protein pump, which is required for luminal acidification of secretory vesicles. Guides the V-type ATPase into specialized subcellular compartments, such as neuroendocrine regulated secretory vesicles or the ruffled border of the osteoclast, thereby regulating its activity. Involved in membrane trafficking and Ca(2+)-dependent membrane fusion. May play a role in the assembly of the V-type ATPase complex. In aerobic conditions, involved in intracellular iron homeostasis, thus triggering the activity of Fe(2+) prolyl hydroxylase (PHD) enzymes, and leading to HIF1A hydroxylation and subsequent proteasomal degradation (By similarity).[UniProtKB:Q15904]
