|---|---|---|---|---|---|
| 0.349 | 4.80E-97 | YGL033W | HOP2 | hom | Meiosis-specific protein that localizes to chromosomes, preventing synapsis between nonhomologous chromosomes and ensuring synapsis between homologs; complexes with Mnd1p to promote homolog pairing and meiotic double-strand break repair |
| 0.348 | 6.86E-96 | YOR091W | TMA46 | hom | Protein of unknown function that associates with translating ribosomes; interacts with GTPase Rbg1p |
| 0.300 | 1.60E-70 | YLL032C | YLL032C | hom | Protein of unknown function that may interact with ribosomes, based on co-purification experiments; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm; YLL032C is not an essential gene |
| 0.292 | 6.25E-67 | YJL159W | HSP150 | hom | O-mannosylated heat shock protein; secreted and covalently attached to the cell wall via beta-1,3-glucan and disulfide bridges; required for cell wall stability; induced by heat shock, oxidative stress, and nitrogen limitation; HSP150 has a paralog, PIR3, that arose from the whole genome duplication |
| 0.273 | 3.02E-58 | YBR020W | GAL1 | hom | Galactokinase; phosphorylates alpha-D-galactose to alpha-D-galactose-1-phosphate in the first step of galactose catabolism; expression regulated by Gal4p; GAL1 has a paralog, GAL3, that arose from the whole genome duplication |
| 0.247 | 1.07E-47 | YDR049W | VMS1 | hom | Component of a Cdc48p-complex involved in protein quality control; exhibits cytosolic and ER-membrane localization, with Cdc48p, during normal growth, and contributes to ER-associated degradation (ERAD) of specific substrates at a step after their ubiquitination; forms a mitochondrially-associated complex with Cdc48p and Npl4p under oxidative stress that is required for ubiquitin-mediated mitochondria-associated protein degradation (MAD); conserved in C. elegans and humans |
