|---|---|---|---|---|---|
| 0.266 | 1.52E-55 | YMR015C | ERG5 | hom | C-22 sterol desaturase, a cytochrome P450 enzyme that catalyzes the formation of the C-22(23) double bond in the sterol side chain in ergosterol biosynthesis; may be a target of azole antifungal drugs |
| 0.260 | 6.35E-53 | YML034C-A_d | YML034C-A_d | hom | Dubious ORF unlikely to encode a functional protein, based on available experimental and comparative sequence data |
| 0.254 | 1.30E-50 | YOR254C | SEC63 | het | Essential subunit of Sec63 complex (Sec63p, Sec62p, Sec66p and Sec72p); with Sec61 complex, Kar2p/BiP and Lhs1p forms a channel competent for SRP-dependent and post-translational SRP-independent protein targeting and import into the ER |
| 0.244 | 1.33E-46 | YLR378C | SEC61 | het | Essential subunit of Sec61 complex (Sec61p, Sbh1p, and Sss1p); forms a channel for SRP-dependent protein import and retrograde transport of misfolded proteins out of the ER; with Sec63 complex allows SRP-independent protein import into ER |
| 0.234 | 1.00E-42 | YIL170W | HXT12 | hom | Possible pseudogene in strain S288C; YIL170W/HXT12 and the adjacent ORF, YIL171W, together encode a non-functional member of the hexose transporter family |
| 0.219 | 1.11E-37 | YNL111C | CYB5 | hom | Cytochrome b5, involved in the sterol and lipid biosynthesis pathways; acts as an electron donor to support sterol C5-6 desaturation |
| 0.218 | 2.24E-37 | YPR064W_d | YPR064W_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
| 0.216 | 9.78E-37 | YLR201C | COQ9 | hom | Protein required for ubiquinone (coenzyme Q) biosynthesis and respiratory growth; localizes to the matrix face of the mitochondrial inner membrane in a large complex with ubiquinone biosynthetic enzymes |
| 0.215 | 2.55E-36 | YIL090W | ICE2 | hom | Integral ER membrane protein with type-III transmembrane domains; required for maintenance of ER zinc homeostasis; necessary for efficient targeting of Trm1p tRNA methyltransferase to inner nuclear membrane; mutations cause defects in cortical ER morphology in both the mother and daughter cells |
| 0.215 | 3.59E-36 | YDL183C | YDL183C | hom | Mitochondrial inner-membrane protein thought to be involved in the formation of an active mitochondrial K+/H+ exchanger (KHE) system; non-essential gene |
| 0.214 | 5.64E-36 | YGL119W | COQ8 | hom | Protein required for ubiquinone biosynthesis and respiratory growth; exhibits genetic interaction with COQ9, suggesting a common function; similar to prokaryotic proteins involved in early steps of ubiquinone biosynthesis; COQ8 has a paralog, YBR230W-A, that arose from the whole genome duplication |
| 0.214 | 7.16E-36 | YML034W | SRC1 | hom | Inner nuclear membrane protein; functions in regulation of subtelomeric genes and is linked to TREX (transcription export) factors; SRC1 produces 2 splice variant proteins with different functions; alternative splicing of SRC1 pre-mRNA is promoted by Hub1p; mutant has aneuploidy tolerance |
| 0.211 | 4.20E-35 | YDL020C | RPN4 | hom | Transcription factor that stimulates expression of proteasome genes; Rpn4p levels are in turn regulated by the 26S proteasome in a negative feedback control mechanism; RPN4 is transcriptionally regulated by various stress responses; relative distribution to the nucleus increases upon DNA replication stress |
| 0.211 | 4.69E-35 | YJL193W_p | YJL193W_p | hom | Putative protein of unknown function, predicted to encode a triose phosphate transporter subfamily member based on phylogenetic analysis; similar to YOR307C/SLY41; deletion mutant has a respiratory growth defect |
| 0.208 | 5.81E-34 | YPR065W | ROX1 | hom | Heme-dependent repressor of hypoxic genes; mediates aerobic transcriptional repression of hypoxia induced genes such as COX5b and CYC7; repressor function regulated through decreased promoter occupancy in response to oxidative stress; contains an HMG domain that is responsible for DNA bending activity; involved in the hyperosmotic stress resistance |
