Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.389 | 8.62E-122 | YER021W | RPN3 | het | Essential, non-ATPase regulatory subunit of the 26S proteasome lid, similar to the p58 subunit of the human 26S proteasome; temperature-sensitive alleles cause metaphase arrest, suggesting a role for the proteasome in cell cycle control |
0.318 | 6.38E-80 | YGL048C | RPT6 | het | ATPase of the 19S regulatory particle of the 26S proteasome; one of six ATPases of the regulatory particle; involved in the degradation of ubiquitinated substrates; bound by ubiquitin-protein ligases Ubr1p and Ufd4p; localized mainly to the nucleus throughout the cell cycle; protein abundance increases in response to DNA replication stress |
0.301 | 2.83E-71 | YOR117W | RPT5 | het | One of six ATPases of the 19S regulatory particle of the 26S proteasome involved in the degradation of ubiquitinated substrates; recruited to the GAL1-10 promoter region upon induction of transcription; similar to human TBP1 |
0.294 | 6.78E-68 | YDL205C | HEM3 | het | Porphobilinogen deaminase, catalyzes the conversion of 4-porphobilinogen to hydroxymethylbilane, the third step in heme biosynthesis; localizes to the cytoplasm and nucleus; expression is regulated by Hap2p-Hap3p, but not by levels of heme |
0.287 | 8.72E-65 | YHR036W | BRL1 | het | Essential nuclear envelope integral membrane protein identified as a suppressor of a conditional mutation in the major karyopherin, CRM1; homologous to and interacts with Brr6p, a nuclear envelope protein involved in nuclear export |
0.277 | 5.30E-60 | YDR427W | RPN9 | het | Non-ATPase regulatory subunit of the 26S proteasome; has similarity to putative proteasomal subunits in other species; null mutant is temperature sensitive and exhibits cell cycle and proteasome assembly defects; protein abundance increases in response to DNA replication stress |
0.260 | 3.86E-53 | YDR394W | RPT3 | het | One of six ATPases of the 19S regulatory particle of the 26S proteasome involved in the degradation of ubiquitinated substrates; substrate of N-acetyltransferase B |
0.254 | 1.07E-50 | YDR047W | HEM12 | het | Uroporphyrinogen decarboxylase, catalyzes the fifth step in the heme biosynthetic pathway; localizes to both the cytoplasm and nucleus; a hem12 mutant has phenotypes similar to patients with porphyria cutanea tarda |
0.240 | 3.70E-45 | YJL054W | TIM54 | het | Component of the mitochondrial TIM22 complex involved in insertion of polytopic proteins into the inner membrane |
0.208 | 3.79E-34 | YFR052W | RPN12 | het | Subunit of the 19S regulatory particle of the 26S proteasome lid; synthetically lethal with RPT1, which is an ATPase component of the 19S regulatory particle; physically interacts with Nob1p and Rpn3p; protein abundance increases in response to DNA replication stress |
0.197 | 8.59E-31 | YKL028W | TFA1 | het | TFIIE large subunit, involved in recruitment of RNA polymerase II to the promoter, activation of TFIIH, and promoter opening |
0.194 | 6.22E-30 | YBR192W | RIM2 | het | Mitochondrial pyrimidine nucleotide transporter; imports pyrimidine nucleoside triphosphates and exports pyrimidine nucleoside monophosphates; member of the mitochondrial carrier family |
0.192 | 4.56E-29 | YFR004W | RPN11 | het | Metalloprotease subunit of the 19S regulatory particle of the 26S proteasome lid; couples the deubiquitination and degradation of proteasome substrates; involved, independent of catalytic activity, in fission of mitochondria and peroxisomes; protein abundance increases in response to DNA replication stress |
0.192 | 4.60E-29 | YDL097C | RPN6 | het | Essential, non-ATPase regulatory subunit of the 26S proteasome lid; required for the assembly and activity of the 26S proteasome; the human homolog (S9 protein) partially rescues Rpn6p depletion; protein abundance increases in response to DNA replication stress |
