DNA repair protein <p> All proteins in this family, for which functions are known, are components in a multiprotein endonuclease complex, usually made up of Rad1 and Rad10 homologues. This complex is used primarily for nucleotide excision repair but also for some aspects of recombinational repair in some species. Most Archaeal species also have homologues of these genes, but the function of the Archaeal proteins is not known, so are not included in this family.</p>
