The RCK1 and RCK2 protein kinase genes from Saccharomyces cerevisiae suppress cell cycle checkpoint mutations in Schizosaccharomyces pombe.

The protein kinase-encoding genes RCK1 and RCK2 from Saccharomyces cerevisiae have been identified as suppressors of Schizosaccharomyces pombe cell cycle checkpoint mutations. Upon expression of these genes, radiation resistance is partially restored in S. pombe mutants with checkpoint deficiencies, but not in mutants with DNA repair defects. Some checkpoint mutants are sensitive to the DNA synthesis inhibitor hydroxyurea, and this sensitivity is also suppressed by RCK1 and RCK2. The degree of suppression can be modulated by varying expression levels. Expression of RCK1 or RCK2 in S. pombe causes cell elongation and decelerated growth. Cells expressing these genes have a single nucleus and a 2n DNA content. We conclude that these genes act in S. pombe to prolong the G2 phase of the cell cycle.[1]
