XPA

DNA repair protein complementing XP-A cells (or XPA) is a protein that in humans is encoded by the XPA gene. ==Function==

Nucleotide excision repair (NER) is a major pathway for repairing a variety of bulky DNA damages including those introduced by UV irradiation. The XPA protein appears to play a key role in NER at sites of damage as a scaffold for other repair proteins in order to ensure that the damages are appropriately excised.
