Regulation of RAD53 by the ATM -Like Kinases MEC1 and TEL1 in Yeast Cell Cycle Checkpoint Pathways

Abstract

Mutants of the Saccharomyces cerevisiae ataxia telangiectasia mutated ( ATM ) homolog MEC1/SAD3/ESR1 were identified that could live only if the RAD53/SAD1 checkpoint kinase was overproduced. MEC1 and a structurally related gene, TEL1 , have overlapping functions in response to DNA damage and replication blocks that in mutants can be provided by overproduction of RAD53 . Both MEC1 and TEL1 were found to control phosphorylation of Rad53p in response to DNA damage. These results indicate that RAD53 is a signal transducer in the DNA damage and replication checkpoint pathways and functions downstream of two members of the ATM lipid kinase family. Because several members of this pathway are conserved among eukaryotes, it is likely that a RAD53 -related kinase will function downstream of the human ATM gene product and play an important role in the mammalian response to DNA damage.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
