Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.452 | 2.25E-168 | YMR185W | RTP1 | het | Protein required for the nuclear import and biogenesis of RNA pol II; conflicting evidence on whether null mutant is viable with elongated buds, or inviable; interacts with Rpb2, Rpb3, Nup116p, Nup100p and components of the R2TP complex (Rvb1p, Rvb2p, Pih1p); similar to human TMCO7 gene |
0.449 | 5.45E-166 | YDR527W | RBA50 | het | Protein involved in transcription; interacts with RNA polymerase II subunits Rpb2p, Rpb3, and Rpb11p; has similarity to human RPAP1 |
0.424 | 2.34E-146 | YOR207C | RET1 | het | Second-largest subunit of RNA polymerase III, which is responsible for the transcription of tRNA and 5S RNA genes, and other low molecular weight RNAs |
0.319 | 7.54E-80 | YAL024C | LTE1 | hom | Protein similar to GDP/GTP exchange factors but without detectable GEF activity; required for asymmetric localization of Bfa1p at daughter-directed spindle pole bodies and for mitotic exit at low temperatures |
0.297 | 3.14E-69 | YOR349W | CIN1 | hom | Tubulin folding factor D involved in beta-tubulin (Tub2p) folding; isolated as mutant with increased chromosome loss and sensitivity to benomyl |
0.282 | 2.42E-62 | YOR262W | GPN2 | het | Putative GTPase with a role in biogenesis of RNA pol II and polIII; may be involved in assembly of RNA polymerases II and III and in their transport into the nucleus; contains a Gly-Pro-Asn motif in the G domain; similar to Npa3p and Gpn3p; highly conserved across species and homologous to human gene GPN2/ATPBD1B; required for establishment of sister chromatid cohesion |
0.257 | 1.45E-51 | YPL241C | CIN2 | hom | GTPase-activating protein (GAP) for Cin4p; tubulin folding factor C involved in beta-tubulin (Tub2p) folding; mutants display increased chromosome loss and benomyl sensitivity; deletion complemented by human GAP, retinitis pigmentosa 2 |
0.250 | 6.62E-49 | YDR041W | RSM10 | het | Mitochondrial ribosomal protein of the small subunit, has similarity to E. coli S10 ribosomal protein; essential for viability, unlike most other mitoribosomal proteins |
0.245 | 4.00E-47 | YER007W | PAC2 | hom | Microtubule effector required for tubulin heterodimer formation, binds alpha-tubulin, required for normal microtubule function, null mutant exhibits cold-sensitive microtubules and sensitivity to benomyl |
0.240 | 3.52E-45 | YML124C | TUB3 | hom | Alpha-tubulin; associates with beta-tubulin (Tub2p) to form tubulin dimer, which polymerizes to form microtubules; expressed at lower level than Tub1p; TUB3 has a paralog, TUB1, that arose from the whole genome duplication |
0.230 | 2.08E-41 | YNL298W | CLA4 | hom | Cdc42p-activated signal transducing kinase of the PAK (p21-activated kinase) family, along with Ste20p and Skm1p; involved in septin ring assembly, vacuole inheritance, cytokinesis, sterol uptake regulation; phosphorylates Cdc3p and Cdc10p |
0.217 | 5.62E-37 | YPR085C | ASA1 | het | Subunit of the ASTRA complex, involved in chromatin remodeling; telomere length regulator involved in the stability or biogenesis of PIKKs such as TORC1 |
0.211 | 5.02E-35 | YNL112W | DBP2 | het | ATP-dependent RNA helicase of the DEAD-box protein family; has a strong preference for dsRNA; involved mRNA decay and rRNA processing; may be involved in suppression of transcription from cryptic initiation sites |
0.193 | 2.61E-29 | YNL148C | ALF1 | hom | Alpha-tubulin folding protein, similar to mammalian cofactor B; Alf1p-GFP localizes to cytoplasmic microtubules; required for the folding of alpha-tubulin and may play an additional role in microtubule maintenance |
