Abstract: Mitotic catastrophe provokes endopolyploidy, giant cell formation and, eventually, delayed cell death. Mitotic catastrophe is induced by defective cell cycle checkpoints and by some anticancer drugs, ionizing radiation and microtubule-destabilizing agents. RAD2 is a yeast homologue of XPG, which is a human endonuclease involved in nucleotide excision repair. Here we show that Rad2p overexpression alone, in the absence of extrinsic DNA damage, causes cell growth arrest and mitotic catastrophe. Interestingly, Rad2p-induced cell growth arrest is not caused by the catalytic activity of Rad2p but rather by its C-terminal region. Cells growth-arrested by Rad2p induction do not show apoptotic phenotypes and deletion of YCA1, a yeast caspase homologue, does not affect cell growth arrest by Rad2p induction. However, Rad2p-induced cell growth arrest is released by rad9 deletion but is not affected by downstream DNA damage checkpoint genes. These observations suggest that RAD2 has a function in coordinating cell cycle regulation and damaged DNA repair. Copyright (c) 2010 John Wiley & Sons, Ltd.
