RAD50

MRX complex DNA-binding subunit, L000001570, YNL250W
Subunit of MRX complex with Mre11p and Xrs2p; complex is involved in processing double-strand DNA breaks in vegetative cells, initiation of meiotic DSBs, telomere maintenance, and nonhomologous end joining; forms nuclear foci upon DNA replication stress
Saccharomyces cerevisiae (S288c)
PREY

SAE2

COM1, ssDNA endodeoxyribonuclease SAE2, L000002892, YGL175C
Endonuclease required for telomere elongation; also required for telomeric 5' C-rich strand resection; involved in processing hairpin DNA structures with MRX complex; involved in double-strand break repair; required for normal resistance to DNA-damaging agents; exists in form of inactive oligomers that are transiently released into smaller active units by a series of phosphorylations; DNA damage triggers removal of Sae2p ensuring that active Sae2p is present only transiently
Saccharomyces cerevisiae (S288c)

Dosage Lethality

A genetic interaction is inferred when over expression or increased dosage of one gene causes lethality in a strain that is mutated or deleted for another gene.

Functional interactions between Sae2 and the Mre11 complex.

Kim HS, Vijayakumar S, Reger M, Harrison JC, Haber JE, Weil C, Petrini JH

The Mre11 complex functions in double-strand break (DSB) repair, meiotic recombination, and DNA damage checkpoint pathways. Sae2 deficiency has opposing effects on the Mre11 complex. On one hand, it appears to impair Mre11 nuclease function in DNA repair and meiotic DSB processing, and on the other, Sae2 deficiency activates Mre11-complex-dependent DNA-damage-signaling via the Tel1-Mre11 complex (TM) pathway. We demonstrate that ... [more]
