    Abstract

    Recently, findings regarding a group of cancer predisposition and chromosome instability syndromes, Nijmegen breakage syndrome (NBS), the ataxia-telangiectasia-like disorder (A-TLD) and ataxia telangiectasia have shed light on the unexpected role of recombinational DNA repair proteins in DNA-damage-dependent cell-cycle regulation. Mutations in the Mre11 complex cause A-TLD and NBS. In addition, functions of the Mre11 complex have been biochemically linked to ATM, the large protein kinase that is defective in ataxia-telangiectasia cells by the observation that Nbs1 is a bona fide substrate of the ATM kinase.
