The F-box protein Dia2 overcomes replication impedance to promote genome stability in Saccharomyces cerevisiae.
The maintenance of DNA replication fork stability under conditions of DNA damage and at natural replication pause sites is essential for genome stability. Here, we describe a novel role for the F-box protein Dia2 in promoting genome stability in the budding yeast Saccharomyces cerevisiae. Like most other F-box proteins, Dia2 forms a Skp1-Cdc53/Cullin-F-box (SCF) E3 ubiquitin-ligase complex. Sys...
متن کاملThe Saccharomyces cerevisiae F-box protein Dia2 is a mediator of S-phase checkpoint recovery from DNA damage.
Cell-cycle progression is monitored by checkpoint pathways that pause the cell cycle when stress arises to threaten the integrity of the genome. Although activation of checkpoint pathways has been extensively studied, our understanding of how cells resume the cell cycle when the stress is resolved is relatively limited. In this study, we identify the Saccharomyces cerevisiae F-box protein Dia2 ...
متن کاملSCF(Dia2) regulates DNA replication forks during S-phase in budding yeast.
Dia2 is an F-box protein, which is involved in the regulation of DNA replication in the budding yeast Saccharomyces cerevisiae. The function of Dia2, however, remains largely unknown. In this study, we report that Dia2 is associated with the replication fork and regulates replication fork progression. Using modified yeast two-hybrid screening, we have identified components of the replisome (Mrc...
متن کاملAn endogenous F-box protein regulates ARGONAUTE1 in Arabidopsis thaliana
ARGONAUTE1 (AGO1) mediates microRNA- and small interfering RNA-directed posttranscriptional gene silencing in Arabidopsis thaliana. Mutant alleles of SQUINT (SQN) slightly reduce AGO1 activity and have weak effects on shoot morphology. A screen for mutations that suppress the sqn phenotype produced loss-of-function mutations in the F-box gene FBW2. Mutations in FBW2 not only suppress sqn but al...
متن کاملThe Amino-Terminal TPR Domain of Dia2 Tethers SCFDia2 to the Replisome Progression Complex
Eukaryotic cells contain multiple versions of the E3 ubiquitin ligase known as the SCF (Skp1/cullin/F box), each of which is distinguished by a different F box protein that uses a domain at the carboxyl terminus to recognize substrates [1, 2]. The F box protein Dia2 is an important determinant of genome stability in budding yeast [3-5], but its mode of action is poorly understood. Here we show ...
