VPH2 | Vacuolar pH 2 | 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]. | Budding yeast |
AVT1 | Amino acid Vacuolar Transport 1 | Overexpressing or deleting AVT1 is sufficient to extend or shorten replicative lifespan, respectively [23172144].
Overexpression of AVT1 prevents mitochondrial dysfunction, prevents alterations in mitochondrial structure and ΔΨ of aged cells even through the vacuolar acidity is reduced in these cells. AVT1 overexpression extends the mean, median and maximum replicative lifespan by 28, 28, and 22%, respectively [23172144].
Deletion of AVT1 accelerates the development of age-induced mitochondrial dysfunction without effecting the kinetics of vacuolar acidity decline and prevents the suppression of mitochondrial dysfunction by VMA1 and VPH2 overexpression without affecting vacuolar acidity. AVT1 deletion decreases mean, median and maximum replicative lifespan by 21, 22, and 12%, respectively [23172144]. | Budding yeast |
VMA1 | Vacuolar Membrane Atpase 1 | Overexpression of VMA1 increases vacuolar acidity and suppresses age-induced mitochondrial dysfunction of aged cells (17 or 18 cell divisions) which requires the V-ATPase activity. VMA1 overexpression significantly increases mean, median and maximum lifespan by 39 - 45%, 39 - 48% and 50 - 60%, respectively. DR (0.5% glucose restriction) does not further increase the lifespan of VMA1 overexpression strain [23172144].

OSH3 | OxySterol binding protein Homolog 3 | Mean replicative lifespan of OSH3 deletion mutant is not significant different from wild type. Overexpression of OSH3 with the promoter of VAC8 shortens mean replicative lifespan ad promotes vacuolar fusion [Xia et al. unpublished]. | Budding yeast |
PEP4 | carboxyPEPtidase Y-deficient 4 | Overexpression of vacuolar aspartyl protease (PEP4) extends chronological lifespan by increasing cytosolic polyamine and S-adenosylmethionine (SAM) levels. Deletion of PEP4 results in both apoptotic and necrotic cell death during chronological aging [21593793]. PEP4 is not DR-essential [18690010]. | Budding yeast |
UGA4 | Utilization of GAba 4 | Deletion of UGA4 does not effect replicative lifespan [21371425]. | Budding yeast |
MXR2 | peptide Methionine sulfoXide Reductase 2 | Deletion or overexpression of MXR2 (alias MsrB) has no effect on replicative lifespan under normal growth conditions. Simulatonous deletion of MXR2 together with MXR1 dramatically reduces replicative lifespan by 63%. Overexpression of MXR2 under DR conditions extends replicative lifespan by 120% [15141092]. | Budding yeast |
TEC1 | Transposon Enhancement Control 1 | Tec1 is a positive regulator of chronological lifespan. Absence of TEC1 causes a significant shortened chronological lifespan, but does not block chronological lifespan extension by rapamycin. TEC(AxY) mutation also reduces chronological lifespan, although not so pronounced as strains lacking TEC1. Rapamycin-induced chronological lifespan extension is almost completely blocked by TEC(AxY) allele [21840851]. | Budding yeast |
SIT4 | Suppressor of Initiation of Transcription 4 | SIT4 deletion slightly increases chronological lifespan and totally abolishes the lifespan shortening due to ISC1 deletion [21707788]. | Budding yeast |

ATH1 | Acid TreHalase | Deletion of ATH1 extend the mean chronological lifespan by 17% (at 30 degree Celsus in BY4742) [22783207].
ATH1 mutants have higher trehalose levels until the end of the post-diauxic growth phase, but reaches a plateau at the level of 50-70% of wild-type in the stationary phase [22783207]. | Budding yeast |

TSL1 | Trehalose Synthase Long chain 1 | Deletion of TSL1 extends the mean chronological lifespan by 43% (at 30 degree Celsus in BY4742) [22783207].
Mutant TSL1 cells have reduced oxidative carbonylation of cellular proteins throughout lifespan. TSL1 mutants have higher trehalose levels, but reaches a plateau at the level of 50-70% of wild-type in the stationary phase.

NTH2 | Neutral TreHalase 2 | Deletion of NTH2 shortens mean chronological lifespan by 39% (at 30 degree Celsus in BY4742) [22783207].
NTH2 mutant cells have elevated trehalose concentration before they enter the non-proliferative stationary growth phase which remained high during the stationary phase. NTH2 deletion cells have no altered ROS levels in pre-quiescent cells [22783207]. | Budding yeast |
TPS1 | Trehalose-6-Phosphate Synthase 1 | Deletion of TPS1 decreases intracellular trehalose concentration and shortens the mean chronological lifespan by 74% (at 30 degree Celsus in BY4742) [22783207]. | Budding yeast |
ESA1 | — | esa1-531 mutant has an even shorter chronological lifespan than PKA1 deletion mutant in both 2% glucose (ad libitum) and water (extreme DR) at 30 degree Celsius, a semipermissive temperature. At the permissive temperature (25 degree Celsius) there is little difference [19303850]. | Budding yeast |
ACH1 | Acetyl CoA Hydrolase 1 | ACH1 deletion cells accumulate a high amount of extracellular acetic acid and display a reduced mean and maximum chronological lifespan. Maximum lifespan is reduced by 32%. Lifespan shortening is completely abrogated by alleviating the acid stress either by a DR regimen that prevents acetic acid production or by transferring chronologically aging mutant cells to water. Deletion of ACH1 is accompanied by reactive oxygen species accumulation, severe mitochondrial damage, and an early insurgence of apoptosis [22754872]. | Budding yeast |
