|---|---|---|---|---|---|
| 0.380 | 2.19E-115 | YGR195W | SKI6 | het | Exosome non-catalytic core component; involved in 3'-5' RNA processing and degradation in both the nucleus and the cytoplasm; has similarity to E. coli RNase PH and to human hRrp41p (EXOSC4) |
| 0.346 | 8.56E-95 | YDL111C | RRP42 | het | Exosome non-catalytic core component; involved in 3'-5' RNA processing and degradation in both the nucleus and the cytoplasm; has similarity to E. coli RNase PH and to human hRrp42p (EXOSC7) |
| 0.325 | 4.48E-83 | YJL099W | CHS6 | hom | Member of the ChAPs (Chs5p-Arf1p-binding proteins) family; part of the exomer complex that mediates export of specific cargo proteins, including Chs3p, from the Golgi to the plasma membrane; CHS6 has a paralog, BCH2, that arose from the whole genome duplication |
| 0.307 | 2.36E-74 | YPR142C_d | YPR142C_d | het | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps the verified ORF RRP15, which is required for ribosomal RNA processing |
| 0.302 | 1.42E-71 | YPL044C_d | YPL044C_d | het | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps the verified gene NOP4/YPL043W |
| 0.291 | 1.29E-66 | YKL172W | EBP2 | het | Required for 25S rRNA maturation and 60S ribosomal subunit assembly; localizes to the nucleolus and in foci along nuclear periphery; constituent of 66S pre-ribosomal particles; cooperates with Rrs1p and Mps3p to mediate telomere clustering by binding Sir4p, but is not involved in telomere tethering |
| 0.285 | 9.96E-64 | YPL043W | NOP4 | het | Nucleolar protein, essential for processing and maturation of 27S pre-rRNA and large ribosomal subunit biogenesis; constituent of 66S pre-ribosomal particles; contains four RNA recognition motifs (RRMs) |
| 0.282 | 1.94E-62 | YMR124W_p | YMR124W_p | hom | Protein of unknown function; GFP-fusion protein localizes to the cell periphery, cytoplasm, bud, and bud neck; interacts with Crm1p in two-hybrid assay; YMR124W is not an essential gene; predicted to have a role in organelle organization |
| 0.282 | 2.24E-62 | YPL066W | RGL1 | hom | Regulator of Rho1p signaling, cofactor of Tus1p; required for the localization of Tus1p during all phases of cytokinesis; green fluorescent protein (GFP)-fusion protein localizes to the bud neck and cytoplasm; null mutant is viable and exhibits growth defect on a non-fermentable (respiratory) carbon source |
| 0.277 | 3.34E-60 | YOL021C | DIS3 | het | Exosome core complex catalytic subunit; possesses both endonuclease and 3'-5' exonuclease activity; involved in 3'-5' RNA processing and degradation in both the nucleus and the cytoplasm; has similarity to E. coli RNase R and to human DIS3; protein abundance increases in response to DNA replication stress |
| 0.276 | 6.49E-60 | YGR158C | MTR3 | het | Exosome non-catalytic core component; involved in 3'-5' RNA processing and degradation in both the nucleus and the cytoplasm; has similarity to E. coli RNase PH and to human hMtr3p (EXOSC6) |
