| Systematic Name | Gene Name | Description |
|---|---|---|
| YGR113W | DAM1 | Essential subunit of the Dam1 complex (aka DASH complex); cooperates with Duo1p and Pse1p to connect the DASH complex with the microtubules (MT); couples kinetochores to the force produced by MT depolymerization, thereby aiding in chromosome segregation; N-terminal staple region is important for self-assembly of the Dam1 complex higher order ring structure that forms around microtubules; Ipl1p target for regulating kinetochore-MT attachments |
| YGR175C | ERG1 | Squalene epoxidase; catalyzes epoxidation of squalene to 2,3-oxidosqualene; plays essential role in ergosterol-biosynthesis pathway and is specific target of antifungal drug terbinafine; directed to ER via guided entry of tail-anchored proteins (GET) pathway; degradation by ERAD triggered by membrane lipid saturation; human SQLE functionally complements the lethality of the erg1 null mutation |
| YLR449W | FPR4 | Nuclear peptidyl-prolyl cis-trans isomerase (PPIase); impacts expression of multiple genes via its role in nucleosome assembly; catalyzes isomerization of proline residues in histones H3 and H4, which affects lysine methylation of those histones; role in rDNA maintenance; PPIase domain acts as a transcriptional repressor when tethered to DNA by lexA, and repressor activity is dependent on PPIase activity; contains a nucleoplasmin-like fold and can form pentamers |
| YKR011C | FPT1 | Chromatin-associated negative regulator of RNA polymerase III assembly; differentially and dynamically occupies RNA polymerase III-transcribed genes; promotes eviction of RNAPIII; occupancy depends on TFIIIB and TFIIIC, not RNAPIII; protein abundance increases in response to DNA replication stress |
| YOR267C | HRK1 | Protein kinase; implicated in activation of the plasma membrane H(+)-ATPase Pma1p in response to glucose metabolism and under acetic acid stress; plays a role in ion homeostasis; maintains pH homeostasis and modulates plasma membrane potential under acetic acid stress; protein abundance increases in response to DNA replication stress |
| YLL026W | HSP104 | Disaggregase; heat shock protein that cooperates with Ydj1p (Hsp40) and Ssa1p (Hsp70) to refold and reactivate denatured, protein aggregates; responds to stresses (heat, ethanol, and sodium arsenite); required for the protein aggregate solid-to-liquid phase transition and dispersal of liquid condensates; involved in [PSI+] propagation; potentiated variants eliminate TDP-43 cytoplasmic aggregates to reduce proteotoxicity; becomes more abundant and forms cytoplasmic foci during replication stress |
| YDR062W | LCB2 | Serine palmitoyltransferase component; responsible along with Lcb1p for the first committed step in sphingolipid synthesis, which is the condensation of serine with palmitoyl-CoA to form 3-ketosphinganine |
| YNL055C | POR1 | Mitochondrial porin and phospholipid scramblase; voltage-dependent anion channel in the outer mitochondrial membrane (OMM) required for maintenance of mitochondrial osmotic stability and membrane permeability; scramblase involved in mitochondrial transbilayer translocation of phospholipids; couples glutathione pools of the intermembrane space (IMS) and the cytosol; phosphorylated; protein abundance increases in response to DNA replication stress; orthologous to human VDAC1 and VDAC2 |
| YKR072C | SIS2 | Negative regulatory subunit of protein phosphatase 1 (Ppz1p); involved in coenzyme A biosynthesis; subunit of the phosphopantothenoylcysteine decarboxylase (PPCDC: Cab3p, Sis2p, Vhs3p) complex and the CoA-Synthesizing Protein Complex (CoA-SPC: Cab2p, Cab3p, Cab4p, Cab5p, Sis2p and Vhs3p); dose-dependent regulator of replicative lifespan; SIS2 has a paralog, VHS3, that arose from the whole genome duplication |
| YDR275W | TLD1 | Protein that regulates lipolysis; inhibits oxidative damage induced by amphotericin B; overexpression increases flocculation, biofilm formation, invasive and pseudohyphal growth; ORF exhibits genomic organization compatible with a translational readthrough-dependent mode of expression; null mutant displays increased translation rate and increased readthrough of premature stop codons; TLD1 has a paralog, IRC23, that arose from the whole genome duplication |
| YGR285C | ZUO1 | Ribosome-associated co-chaperone; zuotin functions in ribosome biogenesis and as a chaperone for nascent polypeptide chains with Ssz1p and Ssb1/2p; subunit of the ribosome-associated complex (RAC) that stimulates Ssb1/2p ATPase activity to facilitate interaction with nascent polypeptide chains emerging from the ribosome exit tunnel; regulates translation upon inhibition of TORC1; contains a DnaJ domain; human gene DNAJC2 partially complements the yeast zuo1 null mutant |
| YGR054W | Eukaryotic initiation factor eIF2A; associates specifically with both 40S subunits and 80S ribosomes, and interacts genetically with both eIF5b and eIF4E; physically interacts with Ssd1p, and associates with mRNAs encoding proteins required for cell wall organization, and some of which require the presence of Ssd1p; translational repressor of cell wall-related proteins; interacts physically and genetically with Xrn1p; homologous to mammalian eIF2A | |
| YKL069W | Methionine-R-sulfoxide reductase; reduces the R enantiomer of free Met-SO, in contrast to Ycl033Cp which reduces Met-R-SO in a peptide linkage; has a role in protection against oxidative stress; capable of binding and degrading patulin, a polyketide mycotoxin, forming E-ascladiol; relative distribution to the nucleus increases upon DNA replication stress |
