Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.168 | 1.36E-22 | YBR099C_d | YBR099C_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; completely overlaps the verified gene MMS4 |
0.154 | 2.78E-19 | YBL088C | TEL1 | hom | Protein kinase primarily involved in telomere length regulation; contributes to cell cycle checkpoint control in response to DNA damage; functionally redundant with Mec1p; regulates P-body formation induced by replication stress; homolog of human ataxia-telangiectasia mutated (ATM) gene, the gene responsible for ataxia telangiectasia (AT) (OMIM 607585) |
0.151 | 1.76E-18 | YLR135W | SLX4 | hom | Endonuclease involved in processing DNA; acts during recombination and repair; cleaves branched structures in a complex with Slx1p; involved interstrand cross-link repair and in Rad1p/Rad10p-dependent removal of 3'-nonhomologous tails during DSBR via single-strand annealing; relative distribution to nuclear foci increases upon DNA replication stress |
0.149 | 3.40E-18 | YBR098W | MMS4 | hom | Subunit of the structure-specific Mms4p-Mus81p endonuclease that cleaves branched DNA; involved in recombination, DNA repair, and joint molecule formation/resolution during meiotic recombination; phosphorylation of the non-catalytic subunit Mms4p by Cdc28p and Cdcp during mitotic cell cycle activates the function of Mms4p-Mus81p |
0.147 | 1.40E-17 | YPL194W | DDC1 | hom | DNA damage checkpoint protein; part of a PCNA-like complex required for DNA damage response, required for pachytene checkpoint to inhibit cell cycle in response to unrepaired recombination intermediates; potential Cdc28p substrate; forms nuclear foci upon DNA replication stress |
0.133 | 1.20E-14 | YOL135C | MED7 | het | Subunit of the RNA polymerase II mediator complex; associates with core polymerase subunits to form the RNA polymerase II holoenzyme; essential for transcriptional regulation |
0.128 | 1.08E-13 | YDR386W | MUS81 | hom | Subunit of the structure-specific Mms4p-Mus81p endonuclease that cleaves branched DNA; involved in DNA repair, replication fork stability, and joint molecule formation/resolution during meiotic recombination; helix-hairpin-helix protein; phosphorylation of the non-catalytic subunit Mms4p by Cdc28p and Cdcp during mitotic cell cycle activates the function of Mms4p-Mus81p |
0.121 | 2.40E-12 | YDL058W | USO1 | het | Essential protein involved in the vesicle-mediated ER to Golgi transport step of secretion; binds membranes and functions during vesicle docking to the Golgi; required for assembly of the ER-to-Golgi SNARE complex |
0.120 | 3.16E-12 | YDL003W | MCD1 | het | Essential alpha-kleisin subunit of the cohesin complex; required for sister chromatid cohesion in mitosis and meiosis; apoptosis induces cleavage and translocation of a C-terminal fragment to mitochondria; expression peaks in S phase |
0.117 | 1.27E-11 | YGL175C | SAE2 | hom | Endonuclease that processes hairpin DNA structures with the MRX complex; involved in meiotic and mitotic double-strand break repair; phosphorylated in response to DNA damage and required for normal resistance to DNA-damaging agents |
0.113 | 4.47E-11 | YDR180W | SCC2 | het | Subunit of cohesin loading factor (Scc2p-Scc4p), a complex required for loading of cohesin complexes onto chromosomes; involved in establishing sister chromatid cohesion during DSB repair via histone H2AX; evolutionarily-conserved adherin |
