Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.592 | 3.56E-316 | YML041C | VPS71 | hom | Nucleosome-binding component of the SWR1 complex, which exchanges histone variant H2AZ (Htz1p) for chromatin-bound histone H2A; required for vacuolar protein sorting |
0.567 | 3.33E-285 | YDR334W | SWR1 | hom | Swi2/Snf2-related ATPase that is the structural component of the SWR1 complex, which exchanges histone variant H2AZ (Htz1p) for chromatin-bound histone H2A |
0.564 | 7.68E-281 | YAL011W | SWC3 | hom | Protein of unknown function, component of the SWR1 complex, which exchanges histone variant H2AZ (Htz1p) for chromatin-bound histone H2A; required for formation of nuclear-associated array of smooth endoplasmic reticulum known as karmellae |
0.559 | 2.35E-275 | YLR085C | ARP6 | hom | Actin-related protein that binds nucleosomes; a component of the SWR1 complex, which exchanges histone variant H2AZ (Htz1p) for chromatin-bound histone H2A |
0.528 | 2.61E-240 | YDR485C | VPS72 | hom | Htz1p-binding component of the SWR1 complex, which exchanges histone variant H2AZ (Htz1p) for chromatin-bound histone H2A; required for vacuolar protein sorting |
0.421 | 4.86E-144 | 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 |
0.387 | 1.86E-120 | YOL012C | HTZ1 | hom | Histone variant H2AZ, exchanged for histone H2A in nucleosomes by the SWR1 complex; involved in transcriptional regulation through prevention of the spread of silent heterochromatin |
0.367 | 2.77E-107 | 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 |
0.342 | 1.96E-92 | YOR349W | CIN1 | hom | Tubulin folding factor D involved in beta-tubulin (Tub2p) folding; isolated as mutant with increased chromosome loss and sensitivity to benomyl |
0.334 | 5.41E-88 | 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 |
0.307 | 3.56E-74 | YJL168C | SET2 | hom | Histone methyltransferase with a role in transcriptional elongation; methylates H3 lysine 36, which suppresses incorporation of acetylated histones and signals for the deacetylation of these histones within transcribed genes; associates with the C-terminal domain of Rpo21p; histone methylation activity is regulated by phosphorylation status of Rpo21p |
0.307 | 4.24E-74 | 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 |
0.297 | 3.80E-69 | YML034C-A_d | YML034C-A_d | hom | Dubious ORF unlikely to encode a functional protein, based on available experimental and comparative sequence data |
0.289 | 1.54E-65 | YGL094C | PAN2 | hom | Essential subunit of the Pan2p-Pan3p poly(A)-ribonuclease complex, which acts to control poly(A) tail length and regulate the stoichiometry and activity of postreplication repair complexes |
0.286 | 4.24E-64 | YJL169W_d | YJL169W_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps the verified gene YJL168C/SET2 |
