About twenty genes participating in checkpoint control are known in yeast Saccharomyces cerevisiae. The involvement of SRM genes in the cell cycle arrest under the action of injurious agents was studied in this work. These genes were earlier defined as genes affecting genetic stability and radiosensitivity. It was shown that mutations srm5/cdc28-srm, srm8/net1-srm, and srm12/hfi1-srm shorten the cell cycle arrest in the presence of DNA damage and influence the checkpoint arrest in G0/S (srm5, srm8), G1/S (srm5, srm8, srm12), S (srm5, srm12), and G2/M (srm5). It seems likely that genes SRM5/CDC28, SRM12/HFI1/ADA1, and SRM8/NET1 are involved in the formation of a cell response to DNA damage, and in checkpoint regulation in particular. |
