Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.704 | 0 | 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 |
0.702 | 0 | YOR330C | MIP1 | hom | Mitochondrial DNA polymerase; conserved C-terminal segment is required for the maintenance of mitochondrial genome; mutations in the human ortholog POLG are associated with Alpers-Huttenlocher syndrome (AHS) and other mitochondrial diseases; Mip1p is the single subunit of mitochondrial DNA polymerase in yeast, in contrast to metazoans in which there is a complex of a catalytic subunit and an accessory subunit |
0.698 | 0 | YDR230W_d | YDR230W_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps the verified gene COX20 |
0.697 | 0 | 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 |
0.684 | 0 | YJL022W_d | YJL022W_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps the verified gene PET130 |
0.670 | 0 | YPL013C | MRPS16 | hom | Mitochondrial ribosomal protein of the small subunit |
0.669 | 0 | YPL132W | COX11 | hom | Mitochondrial inner membrane protein required for delivery of copper to the Cox1p subunit of cytochrome c oxidase; association with mitochondrial ribosomes suggests that copper delivery may occur during translation of Cox1p |
0.665 | 0 | YMR035W | IMP2 | hom | Catalytic subunit of the mitochondrial inner membrane peptidase complex, required for maturation of mitochondrial proteins of the intermembrane space; complex contains Imp1p and Imp2p (both catalytic subunits), and Som1p |
0.651 | 0 | YNR045W | PET494 | hom | Mitochondrial translational activator specific for the COX3 mRNA, acts together with Pet54p and Pet122p; located in the mitochondrial inner membrane |
0.651 | 0 | YDR231C | COX20 | hom | Mitochondrial inner membrane protein, required for proteolytic processing of Cox2p and its assembly into cytochrome c oxidase |
0.648 | 0 | 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 |
0.646 | 0 | YHR116W | COX23 | hom | Mitochondrial intermembrane space protein that functions in mitochondrial copper homeostasis, essential for functional cytochrome oxidase expression; homologous to Cox17p; contains twin cysteine-x9-cysteine motifs |
0.642 | 0 | 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 |
0.640 | 0 | YOR065W | CYT1 | hom | Cytochrome c1, component of the mitochondrial respiratory chain; expression is regulated by the heme-activated, glucose-repressed Hap2p/3p/4p/5p CCAAT-binding complex |
0.631 | 0 | YER058W | PET117 | hom | Protein required for assembly of cytochrome c oxidase |
