BAIT

SLX4

YLR135W
Endonuclease involved in processing DNA; acts during recombination and repair; promotes template switching during break-induced replication (BIR), causing non-reciprocal translocations (NRTs); cleaves branched structures in a complex with Slx1p; involved interstrand cross-link repair and in Rad1p/Rad10p-dependent removal of 3'-nonhomologous tails during DSBR via single-strand annealing; relative distribution to nuclear foci increases upon DNA replication stress
Saccharomyces cerevisiae (S288c)

PPH3

phosphoprotein phosphatase PP4 catalytic subunit PPH3, L000001471, YDR075W
Catalytic subunit of protein phosphatase PP4 complex; Pph3p and Psy2p form active complex, Psy4p may provide substrate specificity; regulates recovery from the DNA damage checkpoint, the gene conversion- and single-strand annealing-mediated pathways of meiotic double-strand break repair and efficient Non-Homologous End-Joining (NHEJ) pathway; involved in activation of Gln3p to alleviate nitrogen catabolite repression; Pph3p and Psy2p localize to foci on meiotic chromosomes
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.

Termination of Replication Stress Signaling via Concerted Action of the Slx4 Scaffold and the PP4 Phosphatase.

In response to replication stress, signaling mediated by DNA damage checkpoint kinases protects genome integrity. However, following repair or bypass of DNA lesions, checkpoint signaling needs to be terminated for continued cell cycle progression and proliferation. In budding yeast, the PP4 phosphatase has been shown to play a key role in preventing hyperactivation of the checkpoint kinase Rad53. In addition, ... [more]
