Synthetic Lethality

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

Publication

The checkpoint protein Ddc2, functionally related to S. pombe Rad26, interacts with Mec1 and is regulated by Mec1-dependent phosphorylation in budding yeast.

Paciotti V, Clerici M, Lucchini G, Longhese MP

DDC2 is a novel component of the DNA integrity checkpoint pathway, which is required for proper checkpoint response to DNA damage and to incomplete DNA replication. Moreover, Ddc2 overproduction causes sensitivity to DNA-damaging agents and checkpoint defects. Ddc2 physically interacts with Mec1 and undergoes Mec1-dependent phosphorylation both in vitro and in vivo. The phosphorylation of Ddc2 takes place in late ... [more]
