Subunit of protein phosphatase PP4 complex; active complex is composed of catalytic subunit Pph3p and Psy2p, with Psy4p apparently providing additional substrate specificity in some cases; regulates recovery from the DNA damage checkpoint and also the gene conversion- and single-strand annealing-mediated pathways of meiotic double-strand break repair; Pph3p and Psy2p localize to foci on meiotic chromosomes; putative homolog of mammalian R3

Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.189 | 2.44E-28 | YDL059C | RAD59 | hom | Protein involved DNA double-strand break repair; repairs breaks in DNA during vegetative growth via recombination and single-strand annealing; anneals complementary single-stranded DNA; forms nuclear foci upon DNA replication stress; required for loading of Rad52p to DSBs; paralog of Rad52p |
0.122 | 1.49E-12 | 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 |
0.118 | 7.38E-12 | 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 |
0.117 | 9.37E-12 | YER095W | RAD51 | hom | Strand exchange protein, forms a helical filament with DNA that searches for homology; involved in the recombinational repair of double-strand breaks in DNA during vegetative growth and meiosis; homolog of Dmc1p and bacterial RecA protein |
0.116 | 1.56E-11 | YGL163C | RAD54 | hom | DNA-dependent ATPase that stimulates strand exchange; modifies the topology of double-stranded DNA; involved in the recombinational repair of double-strand breaks in DNA during vegetative growth and meiosis; member of the SWI/SNF family; forms nuclear foci upon DNA replication stress |
0.113 | 4.53E-11 | YDR304C | CPR5 | hom | Peptidyl-prolyl cis-trans isomerase (cyclophilin) of the endoplasmic reticulum, catalyzes the cis-trans isomerization of peptide bonds N-terminal to proline residues; transcriptionally induced in response to unfolded proteins in the ER |
0.108 | 3.79E-10 | YDR076W | RAD55 | hom | Protein that stimulates strand exchange by stabilizing the binding of Rad51p to single-stranded DNA; involved in the recombinational repair of double-strand breaks in DNA during vegetative growth and meiosis; forms heterodimer with Rad57p |
