The cell wall integrity checkpoint coordinates cell wall synthesis and mitosis in the budding yeast, Saccharomyces cerevisiae. It has been reported that this checkpoint arrests the cell cycle at G2/M phase with repression of the M phase cyclin Clb2p at the transcriptional level, under perturbation of cell wall synthesis. We demonstrate that an override of this checkpoint with accumulation of CLB2 mRNA is induced when negative CLB2 transcription factors are deleted or when positive CLB2 transcription factors are overproduced in cell wall-defective cells. Our data imply that transcription factors for CLB2 are involved in the cell wall integrity checkpoint system and suggest that there are multiple regulation pathways of the checkpoint.
