SUMMARY PARAGRAPH for RAD23

RAD23 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 6. Rad23p and Rad4p form a stoichiometric complex called NEF2 that is required for the incision step of NER in an in vitro reconsituted reaction (7). NEF2 binds specifically to UV-damaged DNA (8, 9). Rad7p and Rad16p form another complex, called NEF4, that binds cooperatively with NEF2 to damaged DNA (10). The in vitro incision reaction is enhanced when both NEF2 and NEF4 are present (10). Rad23p has an N-terminal ubiquitin-like domain that interacts physically with the 26S proteasome (11).

In humans, NER deficiencies are associated with xeroderma pigmentosum (XP) and Cockayne syndrome (6, 12). Human homologs of Rad23p and Rad4p copurify; the Rad4p homolog is encoded by the human XP-C gene (13, 12).
