Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.178 | 2.24E-25 | YGL018C | JAC1 | het | Specialized J-protein that functions with Hsp70 in Fe-S cluster biogenesis in mitochondria, involved in iron metabolism; contains a J domain typical to J-type chaperones; localizes to the mitochondrial matrix |
0.165 | 5.83E-22 | YBL020W | RFT1 | het | Essential integral membrane protein that is required for translocation of Man5GlcNac2-PP-Dol from the cytoplasmic side to the lumenal side of the ER membrane but is not the flippase; mutation is suppressed by expression of human p53 protein |
0.163 | 1.96E-21 | YDL007W | RPT2 | het | One of six ATPases of the 19S regulatory particle of the 26S proteasome involved in the degradation of ubiquitinated substrates; required for normal peptide hydrolysis by the core 20S particle |
0.159 | 2.39E-20 | YCR013C_d | YCR013C_d | het | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; transcription of both YCR013C and the overlapping essential gene PGK1 is reduced in a gcr1 null mutant |
0.150 | 2.72E-18 | YCR054C | CTR86 | het | Essential protein of unknown function; with orthologs in Ashbya gossypii and Candida albicans; similar to human ATXN10, mutations in which cause spinocerebellar ataxia type 10; codon usage corresponds to that observed for yeast genes expressed at low levels; relative distribution to the nucleus increases upon DNA replication stress |
0.148 | 6.72E-18 | YAR008W | SEN34 | het | Subunit of the tRNA splicing endonuclease, which is composed of Sen2p, Sen15p, Sen34p, and Sen54p; Sen34p contains the active site for tRNA 3' splice site cleavage and has similarity to Sen2p and to Archaeal tRNA splicing endonuclease |
0.146 | 1.65E-17 | YBL041W | PRE7 | het | Beta 6 subunit of the 20S proteasome |
0.146 | 1.82E-17 | YDR478W | SNM1 | het | Subunit of RNase MRP, which cleaves pre-rRNA and has a role in cell cycle-regulated degradation of daughter cell-specific mRNAs; binds to the NME1 RNA subunit of RNase MRP |
0.135 | 5.21E-15 | YDL060W | TSR1 | het | Protein required for processing of 20S pre-rRNA in the cytoplasm; associates with pre-40S ribosomal particles; inhibits the premature association of 60S subunits with assembling 40S subunits in the cytoplasm; similar to Bms1p; relocalizes from nucleus to cytoplasm upon DNA replication stress |
0.134 | 6.42E-15 | YOR335C | ALA1 | het | Cytoplasmic and mitochondrial alanyl-tRNA synthetase, required for protein synthesis; point mutation (cdc64-1 allele) causes cell cycle arrest at G1; lethality of null mutation is functionally complemented by human homolog |
0.131 | 3.08E-14 | YHR166C | CDC23 | het | Subunit of the Anaphase-Promoting Complex/Cyclosome (APC/C), which is a ubiquitin-protein ligase required for degradation of anaphase inhibitors, including mitotic cyclins, during the metaphase/anaphase transition |
0.129 | 6.24E-14 | YJR057W | CDC8 | het | Thymidylate and uridylate kinase, functions in de novo biosynthesis of pyrimidine deoxyribonucleotides; converts dTMP to dTDP and dUMP to dUTP; essential for mitotic and meiotic DNA replication; homologous to S. pombe Tmp1p |
0.128 | 8.43E-14 | YML046W | PRP39 | het | U1 snRNP protein involved in splicing, contains multiple tetriatricopeptide repeats |
0.128 | 1.04E-13 | YDR397C | NCB2 | het | Subunit of a heterodimeric NC2 transcription regulator complex with Bur6p; complex binds to TBP and can repress transcription by preventing preinitiation complex assembly or stimulate activated transcription; homologous to human NC2beta |
0.127 | 1.49E-13 | YJL047C-A_p | YJL047C-A_p | hom | Putative protein of unknown function |
