چکیده

We have identified a novel human gene by virtue of its ability to complement the radl-1 checkpoint mutant of Schizosaccharomyces pombe. This gene, called RACH2, rescues the temperature-sensitive lethality of a radl-1 weel-50 double mutant of S. pombe. Expression of RACH2 in S. pombe radl-1 strains partially restores UV resistance to the radl-1 mutant strain. Expression of RACH2 in a radl-1 cdc25-22 double mutant partially restores the dose-dependent delay in mitotic entry after irradiation that is lost in radl-1 checkpointdeficient mutants. Overexpression of RACH2 in human tissue culture cells induces apoptosis.

Functions of fission yeast orp2 in DNA replication and checkpoint control.

orp2 is an essential gene of the fission yeast Schizosaccharomyces pombe with 22% identity to budding yeast ORC2. We isolated temperature-sensitive alleles of orp2 using a novel plasmid shuffle based on selection against thymidine kinase. Cells bearing the temperature-sensitive allele orp2-2 fail to complete DNA replication at a restrictive temperature and undergo cell cycle arrest. Cell cycle ...

Caffeine-mediated override of checkpoint controls. A requirement for rhp6 (Schizosaccharomyces pombe).

Cells exposed to inhibitors of DNA synthesis or suffering DNA damage are arrested or delayed in interphase through the action of checkpoint controls. If the arrested cell is exposed to caffeine, relatively normal cell cycle progression is resumed and, as observed in checkpoint control mutants, loss of checkpoint control activity is associated with a reduction in cell viability. To address the m...

Regulation of meiotic progression by the meiosis-specific checkpoint kinase Mek1 in fission yeast.

During the eukaryotic cell cycle, accurate transmission of genetic information to progeny is ensured by the operation of cell cycle checkpoints. Checkpoints are regulatory mechanisms that block cell cycle progression when key cellular processes are defective or chromosomes are damaged. During meiosis, genetic recombination between homologous chromosomes is essential for proper chromosome segreg...

The fission yeast cdc19+ gene encodes a member of the MCM family of replication proteins.

We have cloned and characterized the fission yeast cdc19+ gene. We demonstrate that it encodes a structural homologue of the budding yeast MCM2 protein. In fission yeast, the cdc19+ gene is constitutively expressed, and essential for viability. Deletion delays progression through S phase, and cells arrest in the first cycle with an apparent 2C DNA content, with their checkpoint control intact. ...

Coordination of DNA damage tolerance mechanisms with cell cycle progression in fission yeast

DNA damage tolerance (DDT) mechanisms allow cells to synthesize a new DNA strand when the template is damaged. Many mutations resulting from DNA damage in eukaryotes are generated during DDT when cells use the mutagenic translesion polymerases, Rev1 and Polζ, rather than mechanisms with higher fidelity. The coordination among DDT mechanisms is not well understood. We used live-cell imaging to s...
