VPH2

Symbol: VPH2
Name: Vacuolar pH 2
Alias: CLS10; VMA12
Entrez gene ID: 853741
Ensembl gene ID: YKL119C
Species: Yeast (Taxid: 4932)

Function:
VPH2 is and endoplasmic-reticulum-localized integral membrane protein required for the assembly and therefore also activity of the vacuolar H+-ATPase (V-ATPase) [9325326].

Observation:

Overexpression of VPH2 increases the levels of assembled V-ATPase at the vacuolar membrane, increases vacuolar acidity and suppresses age-induced mitochondrial dysfunction of aged cells (17 or 18 cell divisions) which requires the V-ATPase activity. VPH2 overexpression significantly increases mean, median and maximum replicative lifespan by 23, 25 and 34%, respectively [23172144].



Interventions:
  • VPH2 overexpression +23.1% +25.0% +34.0%

  • Assays: Replicative Lifespan
    Mean: +23.1
    Median: +25.0
    Maximum: +34.0

    Classification:
  • Aging-Suppressor
  • Positive Aging-Suppressor
