CDC13

EST4, telomere-binding protein CDC13, L000000253, YDL220C
Single stranded DNA-binding protein found at TG1-3 telomere G-tails; key roles in regulation of telomerase, telomere end protection, conventional telomere replication; regulates telomere replication through recruitment of specific sub-complexes, essential function is telomere capping; forms homodimer via N-terminus; disruption of dimerization leads to short telomeres; autophagy and proteasome are involved in Cdc13p degradation; differentially phosphorylated through cell cycle
Saccharomyces cerevisiae (S288c)

XRS2

L000002489, YDR369C
Protein required for DNA repair; component of the Mre11 complex, which is involved in double strand breaks, meiotic recombination, telomere maintenance, and checkpoint signaling
Saccharomyces cerevisiae (S288c)

Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

MRX protects telomeric DNA at uncapped telomeres of budding yeast cdc13-1 mutants.

Foster SS, Zubko MK, Guillard S, Lydall D

MRX, an evolutionally conserved DNA damage response complex composed of Mre11, Rad50 and Xrs2, is involved in DNA double strand break (DSB) repair, checkpoint activation and telomere maintenance. At DSBs, MRX plays a role in generating single stranded DNA (ssDNA) and signalling cell cycle arrest. Here we investigated whether MRX also contributes to generating ssDNA or signalling cell cycle arrest ... [more]
