Cell cycle checkpoints are regulatory mechanisms that prevent cell cycle progression in the presence of DNA damage or incompletely replicated DNA. Many of the genes required for cell-cycle arrest are also involved in DNA repair, apoptosis, and induction of transcription. In yeast and humans, hRAD9 plays a role in cell cycle arrest during the G2 phase before entry into mitosis. Phosphorylated hRAD9 is found in the nucleus after DNA damage, and forms DNA damage-responsive complexes with other putative checkpoint control proteins, such as hRAD1 and hHUS1. Expression of hRAD9 in S. pombe rad9::ura4+ cells restores resistance to the DNA synthesis inhibitor hydroxyurea and gamma rays. In addition, hRAD9 binds the anti-apoptotic proteins, Bcl-2 and Bcl-xL , and antisense hRAD9 RNA suppresses DNA-damage induced cell death. Thus, hRAD9 may be an important component of protein complexes that regulate cell cycle progression, as well as apoptosis, in response to DNA damage.
