Human DDB (Damaged DNA Binding protein) is a heterodimer of 48 and 127kDa subunits whose activity is absent from cell strains derived from a subset of Xeroderma Pigmentosum (XP) complementation group E individuals (Ddb−) [Keeney, S., Wein, H., and Linn, S., (1992). Mut. Res. 273, 49–56]. Whereas in vivo DNA repair appears to be compromised in both Ddb−and Ddb+XPE cells, DDB activity is not necessary for nucleotide excision repair (NER) in vitro. In this study, the presence of a specific UV-damaged DNA binding activity in mouse cell-free extracts that is comparable to the activity observed in HeLa cells was demonstrated. The mouse DDB2 cDNA, coding for DDB p48 subunit, was cloned and the partial genomic structure of DDB2 was obtained. A search of current databases revealed amino acid sequences of mouse and Drosophila predicted p127 homologues, but not of a Drosophila p48 homologue. The alignment of these higher eukaryotic p127 sequences uncovered the presence of three highly conserved domains in the p127 polypeptides which we hypothesize could function in DNA binding, transcription-transactivation, and protein-protein interaction, respectively.
