| AAT1 | Aspartate AminoTransferase 1 | Overexpression of AAT1 extends replicative lifespan by 25% and does not synergize with 0.5% glucose restriction [18381895]. | 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 |
| BMH2 | Brain Modulosignalin Homologue 2 | Overexpressing 14-3-3 protein, Bmh2, significantly extends median chronological lifespan by activating stress response [19805817]. | Budding yeast |
| ERG2 | ERGosterol biosynthesis 2 | Overexpression of ERG2 with the promoter of ERG6 (Perg6-ERG2) extends replicative lifespan and this effect was overlapping with moderate DR, because DR can not extend the lifespan of this mutant [Tang et al., unpublished].
Perg6-ERG2 does not extend the lifespan significantly on normal medium, but it reverses the effect of DR. DR greatly shortens the lifespan of Perg6-ERG2 mutants. Perg6-ERG2 shortens the lifespan of nyv1 deletion mutations [Xia et al. unpublished].
Deletion of OSH5 greatly shortens the lifespan of Perg6-ERG2. SIR2 overxpression extends the lifespan of Perg6-ERG2 [Xia et al. unpublished]. | Budding yeast |
| FIS1 | fission 1 (mitochondrial outer membrane) homolog (S. cerevisiae) | Deletion of FIS1 prolongs significantly mean and maximum lifespan by 13 and 29% as well as improves the fitness of old mother cells (in BY4741) [17173038]. | Budding yeast |
| GUT2 | Glycerol UTilization 2 | Overexpression of GUT2 extends replicative lifespan by 25% and does not synergize with 0.5% glucose restriction [18381895]. | Budding yeast |
| HAP4 | Heme Activator Protein 4 | Overexpression of HAP4 from the ADH1 promoter extends lifespan of PSY316 strain approximately 40% under growth conditions favoring fermentation (2% glucose). Overexpression of HAP4 increases replicative lifespan, but is non-additive with 0.5% glucose restriction in lifespan extension. Lifespan extension by HAP4 overexpression requires SIR2 [12124627]. HAP4 deletion suppresses replicative lifespan extension to 30% and 33% on 0.1% glucose and on elimination of non-essential amino acids, respectively [20178842]. HAP4 overexpressing cells demonstrate a transcriptional response resembling cells undergoing diauxic shift, consume more oxygen, and exhibit increased Sir2-dependent transcriptional silencing at telomeres and rDNA [12124627]. | Budding yeast |
| HPR1 | HyPerRecombination 1 | Deletion of HPR1 decreases replicative lifespan [11756539] | Budding yeast |
| HST2 | Homolog of SIR Two (SIR2) 2 | HST2 overexpression extends replicative lifespan. 0.5% glucose restriction does not increase lifespan of sir2;fob1;hst2 triple mutants [16051752]. DR increases lifespan of all four sir2;fob1;hstX(X = sirtuin) triple mutants [16741098; 17129213]. | Budding yeast |
| IME1 | Inducer of MEiosis 1 | Transient overexpression of IME1 resets the replicative lifespan of old cells back to that of young cells [21700873]. | Budding yeast |
| LAG2 | Protein involved in determination of longevity | Deletion of LAG2 in haploid SP1 strain does not affect growth, but results in a 50% decrease in the mean and maximum replicative lifespan. When LAG2 is overexpressed, the mean and maximum replicative lifespan is extended by about 36% and 54%, respectively. Overexpression induced at generation 12 similarly increases replicative lifespan [8760941]. | Budding yeast |
| LAT1 | — | LAT1 is suggested to play a role in lifespan extension of DR. Deleting LAT1 abolishes replicative lifespan extension induced by 0.5% and 0.05% glucose restriction. In contrast, overexpressing Lat1 extends replicative lifespan, and this lifespan extension was not further increased by 0.5% glucose restriction. Similar to DR, replicative lifespan extension by LAT1 overexpression largely requires mitochondrial respiration [17200108]. Overexpressing LAT1 extends lifespan (20% mean lifespan increase) and this lifespan extension is not further increased by DR. Similar to DR, lifespan extension by Lat1 overexpression largely requires mitochondrial respiration indicating mitochondrial metabolism plays an important role in DR. Interestingly, LAT1 overexpression does not require the Sir2 family to extend lifespan. Lat1 is also a limiting longevity factor in non-dividing cells in that overexpressing LAT1 extends cell survival during prolonged culture at stationary phase. | Budding yeast |
| MDH1 | Malate DeHydrogenase 1 | Overexpression of MDH1 extends replicative lifespan by 25% and does not synergize with 0.5% glucose restriction [18381895]. | Budding yeast |
| MPT5 | — | Overexpression of MPT5 from the ADH promoter extends replicative lifespan by about 20% in W303R [11805047] and by 25% in PSY142 [9150138], whereas the deletion of MPT5 shortens lifespan by about 50% [9150138; 7859289]. MPT5 deletion decreases average chronological lifespan by 50%, which is rescued to the wild-type level by PKC1 overexpression [17172436].
MPT5 mutants are temperature sensitive [7845352], hypersensitive to mating pheromone [9154842], and null mutants exhibit increased silencing at telomeres and decreased rDNA silencing [9584615]. Deletion of MPT5 is synthetical lethal with mutation of either SWI4, SWI6, or CCR4 in an ssd1-d background [11805047]. MPT5 overexpression suppresses the temperature phenotype of POP2 mutant [9504907]. MPT5 is required for relocalization of the SIR complex to the nucleolus in sir4-42 strain [7859289]. | Budding yeast |
| MXR1 | peptide Methionine sulfoXide Reductase 1 | Deletion of MXR1 (alias MsrA) decreases by 25% and overexpression slightly increases the replicative lifespan [15141092]. Deletion of MXR1 decreases replicative lifespan [19049972]. MXR1 deletion decreases replicative lifespan on either glucose or lactate as carbon source [20799725]. Although deletion or overexpression of MXR2 (alias MsrB) has no effect under normal growth conditions, the simultaneous deletion of MXR1 and MXR2 reduces the lifespan by 63% [15141092]. | Budding yeast |
| NDE1 | NADH Dehydrogenase, External 1 | Overexpression of NDE1 and NDE2 increases intracellular NAD/NADH ratio by lowering NADH concentration and increases replicative lifespan by 20-25%. This lifespan extension is non-additive 0.5% glucose restriction [14724176]. Deletion of NDE1 extends chronological lifespan [16436509]. | Budding yeast |
| NDE2 | NADH Dehydrogenase, External 2 | Overexpression of NDE1 and NDE2 increases intracellular NAD/NADH ratio by lowering NADH concentration and increases replicative lifespan by 20-25%. This lifespan extension is non-additive with 0.5% glucose restriction [14724176]. | Budding yeast |
| NDT80 | Non-DiTyrosine 80 | Transient overexpression of NDT80 rejuvenates old cells [21700873]. | Budding yeast |
| NNT1 | Nicotinamide N-methylTransferase 1 | Deletion of NNT1 decreases mean and maximum lifespan by 9 and 19%. 0.5% glucose DR extends the mean and maximum lifespan of NNT1 deletion mutants by 35 and 40%. Overexpression of NNT1 by 5-fold extends mean and maximum replicative lifespan by 18 and 23%, which is approximately of the same magnitude as the lifespan extension obtained from DR. DR in NNT1 overexpression mutant fails to significantly affect the lifespan and only results in extended mean lifespan by 12% and reduced maximum lifespan by 11%. NNT1 overexpression increases rDNA silincing, whereas deletion decreases rDNA silencing. Overexpression of human nicotinamide N-methyltransferase also increases rDNA silencing [12736687]. | Budding yeast |
| NPT1 | Nicotinate PhosphoribosylTransferase 1 | Increased dosage of NPT1 increases SIR2-dependent silencing, stabilizes the rDNA locus and extends replicative lifespan by up to 60%. 0.5% glucose restriction does not significantly further increase replicative lifespan of NPT1 overexpression [11884393]. NPT1 deletion decreases replicative lifespan by 50% [17482543] as well as chronological lifespan [17110466]. Deletion of NPT1 shortens the lifespan in W303R. Replicative lifespan extension of cdc25-10 mutation (assumed to act as a genetic DR-mimetic) is cancelled out by NPT1 deletion [11000115].
NPT1 mutation results in loss of telomere and rDNA silencing [10841563], an effect that is likely caused by a loss of SIR2 activty due to decreased NAD levels. Mutation of NPT1 is synthetical lethal with mutation of QPT1 [11000115]. | Budding yeast |
| OSH6 | OxySterol binding protein Homolog 6 | Elevation of OSH6 levels by an ERG6 promoter extends mean, median and maximum replicative lifespan by 39, 52 and 18% which is non-additive with 0.5% glucose restriction. It also extends the lifespan of NYV1 mutant [Geber et al., unpublished].
The long lifespan of Perg6-OSH6 is not further extended by deletion of TOR1 [22622083].
OSH6 overexpression decreases total cellular sterol content and reduces Lst8 protein levels. The CC domain of Osh6 is dispensable for longevity. Deletion of the CC domain leads Osh6 to the late endosome. [Fusheng Tang, personal communication].
OSH6 deletion does not affect lifespan under normal conditions, but it abrogates the lifespan extension by 0.5% glucose restriction [Xia et al. unpublished].
Perg6-OSH6 osh5 double mutant have a lifespan significantly shorter than that of Perg6-OSH6 [Xia et al. upublished]. | Budding yeast |
| OSH7 | OxySterol binding protein Homolog 7 | Overexpression of OSH7 extends mean replicative lifespan. PERG6-OSH7 does not extend the maximum lifespan significantly [Xia et al., unpublished].
Deletion of the CC domain of Osh7 (Perg6-OSH7-ORD) greatly shortens the lifespan. Deletion of the Osh7's CC domain decreases lifespan (Perg6-OSH7-ORD) shortens the lifespan [Tang et al., personal communication].
Osh7 interacts with the late endosome ATPase Vps4 by their C-terminal coiled-coil (CC) domain. | 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 |
| PGA3 | Processing of Gas1p and ALP | Low glucose condition induces expression and activity of plasma membrane NADH coenzyme Q reductase (PGA3). Overexpression of PGA3 extends replicative and chronological lifespan by 20-30% [19239415]. | Budding yeast |
| PMR1 | High affinity Ca2+/Mn2+ P-type ATPase required for Ca2+ and Mn2+ transport into Golgi; involved in Ca2+ dependent protein sorting and processing; mutations in human homolog ATP2C1 cause acantholytic skin condition Hailey-Hailey disease | Deletion of PMR1 increses the replicative lifespan by 40% in the alpha strain and by 15% in the a strain. Overexpression of PMR1 extends the lifespan [21918615]. | Budding yeast |
