The DNA damage-binding protein from HeLa cells is associated with polypeptides of relative mass 124,000 (DDB1) and 41,000 (DDB2) as determined by SDS-polyacrylamide gels. To test whether the DNA-repair defect in the subset of XPE patients that lack DNA damage-binding activity is caused by a defect in DDB, Keeney et al. (1994) injected purified human DDB protein into XPE cells.
