Harmonizome 3.0

xeroderma pigmentosum, complementation group A

This gene encodes a zinc finger protein plays a central role in nucleotide excision repair (NER), a specialized type of DNA repair. NER is responsible for repair of UV radiation-induced photoproducts and DNA adducts induced by chemical carcinogens and chemotherapeutic drugs. The encoded protein interacts with DNA and several NER proteins, acting as a scaffold to assemble the NER incision complex at sites of DNA damage. Mutations in this gene cause Xeroderma pigmentosum complementation group A (XP-A), an autosomal recessive skin disorder featuring hypersensitivity to sunlight and increased risk for skin cancer.

XPA binding protein 2

Involved in DNA-templated transcription; mRNA splicing, via spliceosome; and transcription-coupled nucleotide-excision repair. Located in nucleoplasm. Part of U2-type catalytic step 2 spliceosome. [provided by Alliance of Genome Resources, Mar 2025]
