In molecular biology the XPG-I is a protein domain found on Xeroderma Pigmentosum Complementation Group G (XPG) protein. The XPG protein is an endonuclease which repairs DNA damage caused by ultraviolet light (UV light). The XPG protein repairs DNA by a process called Nucleotide Excision Repair. Mutations in the protein commonly cause Xeroderma Pigmentosum which often lead to skin cancer.
