Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.215 | 2.96E-36 | YML025C | YML6 | het | Mitochondrial ribosomal protein of the large subunit, has similarity to E. coli L4 ribosomal protein and human mitoribosomal MRP-L4 protein; essential for viability, unlike most other mitoribosomal proteins |
0.191 | 8.84E-29 | YGR216C | GPI1 | het | Membrane protein involved in the synthesis of N-acetylglucosaminyl phosphatidylinositol (GlcNAc-PI), the first intermediate in the synthesis of glycosylphosphatidylinositol (GPI) anchors; human and mouse GPI1p are functional homologs |
0.174 | 3.26E-24 | YGL114W_p | YGL114W_p | hom | Putative protein of unknown function; predicted member of the oligopeptide transporter (OPT) family of membrane transporters |
0.173 | 6.28E-24 | YDR242W | AMD2 | hom | Putative amidase |
0.153 | 4.34E-19 | YDR056C_p | YDR056C_p | hom | Putative protein of unknown function; green fluorescent protein (GFP)-fusion protein localizes to the endoplasmic reticulum; YDR056C is not an essential protein |
0.152 | 6.62E-19 | YOR298C-A | MBF1 | hom | Transcriptional coactivator; bridges the DNA-binding region of Gcn4p and TATA-binding protein Spt15p; suppressor of frameshift mutations; protein abundance increases in response to DNA replication stress |
0.147 | 1.11E-17 | YER067C-A_d | YER067C-A_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps the uncharacterized ORF YER067W |
0.140 | 3.54E-16 | YOR271C_p | FSF1_p | hom | Putative protein, predicted to be an alpha-isopropylmalate carrier; belongs to the sideroblastic-associated protein family; non-tagged protein is detected in purified mitochondria; likely to play a role in iron homeostasis |
0.139 | 5.51E-16 | YBR262C | AIM5 | hom | Mitochondrial inner membrane protein; subunit of the mitochondrial inner membrane organizing system (MitOS, MICOS, or MINOS), a scaffold-like structure on the intermembrane space side of the inner membrane which has a role in the maintenance of crista junctions and inner membrane architecture |
0.138 | 9.49E-16 | YHR122W | CIA2 | het | Component of cytosolic iron-sulfur protein assembly (CIA) machinery; acts at a late step of Fe-S cluster assembly; forms the CIA targeting complex with Cia1p and Met18p that directs Fe-S cluster incorporation into a subset of proteins involved in methionine biosynthesis, DNA replication and repair, transcription, and telomere maintenance; ortholog of human FAM96B |
0.136 | 3.41E-15 | YML100W | TSL1 | hom | Large subunit of trehalose 6-phosphate synthase/phosphatase complex; Tps1p-Tps2p complex converts uridine-5'-diphosphoglucose and glucose 6-phosphate to trehalose; mutant has aneuploidy tolerance; protein abundance increases in response to DNA replication stress; TSL1 has a paralog, TPS3, that arose from the whole genome duplication |
0.134 | 6.26E-15 | YGL017W | ATE1 | hom | Arginyl-tRNA-protein transferase, catalyzes post-translational conjugation of arginine to the amino termini of acceptor proteins which are then subject to degradation via the N-end rule pathway |
0.134 | 6.95E-15 | YER172C | BRR2 | het | RNA-dependent ATPase RNA helicase (DEIH box); required for disruption of U4/U6 base-pairing in native snRNPs to activate the spliceosome for catalysis; homologous to human U5-200kD |
0.132 | 1.39E-14 | YBL068W | PRS4 | hom | 5-phospho-ribosyl-1(alpha)-pyrophosphate synthetase, synthesizes PRPP, which is required for nucleotide, histidine, and tryptophan biosynthesis; one of five related enzymes, which are active as heteromultimeric complexes; PRS4 has a paralog, PRS2, that arose from the whole genome duplication |
0.127 | 1.71E-13 | YML083C | YML083C | hom | Protein of unknown function; transcriptionally regulated by Upc2p via an upstream sterol response element; strong increase in transcript abundance during anaerobic growth compared to aerobic growth; cells deleted for YML083C do not exhibit growth defects in anerobic or anaerobic conditions |
