The Schizosaccharomyces pombe rad17 is a checkpoint protein critical for maintenance of genomic stability. Since the loss of checkpoint control is a common feature of tumor cells, we investigated the biological function of the human homolog hRAD17. Expression of hRAD17 in a fission yeast rad17 deleted strain reduced growth of yeast colonies and caused slower progression through cell cycle. Immunoprecipitated hRad17 exhibited exonuclease activity. hRAD17 delayed growth of NIH3T3 fibroblasts transformed by the H-ras oncogene in nude mice. Our results support that hRAD17, similarly to other human genes involved in checkpoint mechanisms, plays a role in control of tumor growth.
