RAD4 encodes a protein that acts in nucleotide excision repair (NER) of UV-damaged DNA. In NER, damaged DNA is excised by incision of the DNA on either side of the lesion followed by unwinding by DNA helicases; the process of NER is reviewed in 7. Rad4p and Rad23p form a stoichiometric complex called NEF2 that is required for the incision step of NER in an in vitro reconsituted reaction (8). NEF2 binds specifically to UV-damaged DNA (9, 10). Rad7p and Rad16p form another complex, called NEF4, that binds cooperatively with NEF2 to damaged DNA (11). The in vitro incision reaction is enhanced when both NEF2 and NEF4 are present (11). rad4 mutants are extremely sensitive to UV and completely defective in the incision step of NER (12).

In humans, NER deficiencies are associated with xeroderma pigmentosum (XP) and Cockayne syndrome (7, 13). RAD4 is homologous to the gene associated with XP-C (13); the human Rad4p homolog copurifies with a protein homologous to Rad23p (14). Rad4p homologs have also been found in several other eukaryotes, including S. pombe (15) and Drosophila (16).
