Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.304 | 5.89E-73 | YPL013C | MRPS16 | hom | Mitochondrial ribosomal protein of the small subunit |
0.300 | 1.16E-70 | YMR151W_d | YIM2_d | hom | Dubious open reading frame, unlikely to encode a protein; not conserved in closely related Saccharomyces species; 5% of ORF overlaps the verified gene IMP1 |
0.296 | 4.26E-69 | YJL166W | QCR8 | hom | Subunit 8 of ubiquinol cytochrome-c reductase complex, which is a component of the mitochondrial inner membrane electron transport chain; oriented facing the intermembrane space; expression is regulated by Abf1p and Cpf1p |
0.294 | 6.75E-68 | YEL059C-A | SOM1 | hom | Subunit of the mitochondrial inner membrane peptidase, which is required for maturation of mitochondrial proteins of the intermembrane space; Som1p facilitates cleavage of a subset of substrates; contains twin cysteine-x9-cysteine motifs |
0.294 | 7.07E-68 | YHR050W-A_p | YHR050W-A_p | hom | Protein of unknown function; identified by expression profiling and mass spectrometry |
0.289 | 1.41E-65 | YDR518W | EUG1 | hom | Protein disulfide isomerase of the endoplasmic reticulum lumen; EUG1 has a paralog, PDI1, that arose from the whole genome duplication; function overlaps with that of Pdi1p; may interact with nascent polypeptides in the ER |
0.284 | 3.67E-63 | YNL213C | RRG9 | hom | Protein of unknown function; null mutant lacks mitochondrial DNA and cannot grow on glycerol; the authentic, non-tagged protein is detected in highly purified mitochondria in high-throughput studies |
0.284 | 3.90E-63 | YDR375C | BCS1 | hom | Protein translocase and chaperone required for Complex III assembly; member of the AAA ATPase family; forms a homo-oligomeric complex in the mitochondrial inner membrane that translocates the C-terminal domain of Rip1p from the matrix across the inner membrane, and then delivers it to an assembly intermediate of respiratory Complex III in an ATP-dependent reaction; also required for assembly of the Qcr10p subunit; mutations in human homolog BCS1L linked to neonatal diseases |
0.280 | 3.37E-61 | YGR183C | QCR9 | hom | Subunit 9 of the ubiquinol cytochrome-c reductase complex, which is a component of the mitochondrial inner membrane electron transport chain; required for electron transfer at the ubiquinol oxidase site of the complex |
0.278 | 2.13E-60 | YJR120W | YJR120W | hom | Protein of unknown function; essential for growth under anaerobic conditions; mutation causes decreased expression of ATP2, impaired respiration, defective sterol uptake, and altered levels/localization of ABC transporters Aus1p and Pdr11p |
0.272 | 5.76E-58 | YJL023C | PET130 | hom | Protein required for respiratory growth; the authentic, non-tagged protein is detected in highly purified mitochondria in high-throughput studies |
0.271 | 1.38E-57 | YLL009C | COX17 | hom | Copper metallochaperone that transfers copper to Sco1p and Cox11p for eventual delivery to cytochrome c oxidase; contains twin cysteine-x9-cysteine motifs |
0.266 | 2.22E-55 | YGR220C | MRPL9 | hom | Mitochondrial ribosomal protein of the large subunit |
0.262 | 8.46E-54 | YPL215W | CBP3 | hom | Mitochondrial protein required for assembly of cytochrome bc1 complex; forms a complex with Cbp6p that binds to mt ribosomes near the polypeptide tunnel exit and promotes efficient translation of the COB mRNA; Cbp3p-Cbp6p complex also interacts with newly synthesized cytochrome b (Cobp) and Cbp4p to promote assembly of Cobp into the cytochrome bc1 complex |
0.260 | 7.08E-53 | YPL189C-A | COA2 | hom | Cytochrome oxidase assembly factor; null mutation results in respiratory deficiency with specific loss of cytochrome oxidase activity; functions downstream of assembly factors Mss51p and Coa1p and interacts with assembly factor Shy1p |
