PCH2

L000004274, YBR186W
Hexameric ring ATPase that remodels chromosome axis protein Hop1p; nucleolar component of the pachytene checkpoint, which prevents chromosome segregation when recombination and chromosome synapsis are defective; also represses meiotic interhomolog recombination in rDNA; required for meiotic double-stranded break formation

MRE4, serine/threonine protein kinase MEK1, L000001062, L000001148, YOR351C
Meiosis-specific serine/threonine protein kinase; functions in meiotic checkpoint, promotes recombination between homologous chromosomes by suppressing double strand break repair between sister chromatids; stabilizes Hop1-Thr318 phosphorylation to promote interhomolog recombination and checkpoint responses during meiosis

Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

Publication

Mek1 kinase governs outcomes of meiotic recombination and the checkpoint response.

Wu HY, Ho HC, Burgess SM

Homologous recombination promotes proper segregation of chromosomes during meiosis. Programmed double-strand breaks (DSBs) initiate recombination and are repaired preferentially using the homolog rather than the sister chromatid template. In yeast, activation of Mek1 kinase upholds this bias. Mek1 is also a proposed effector kinase in the recombination checkpoint that responds to aberrant DNA and/or axis structures. Elucidating a role for ... [more]

Throughput

  • Low Throughput

Ontology Terms

  • phenotype: chromosome/plasmid maintenance (APO:0000143)
  • phenotype: protein/peptide accumulation (APO:0000149)
  • phenotype: viability (APO:0000111)

Additional Notes

  • genetic complex
  • overexpression of Mek1-GST can partially rescue the reduced levels of various proteins, fast progression through mitosis and decrease in crossover products during DNA replication seen in a rad17/pch2 double mutant
