Supplementary information

The XPA (xeroderma pigmentosum group A) protein also known as DNA repair protein complementing XP-A cells is a vital player in the nucleotide excision repair (NER) machinery. It has a molecular mass of approximately 31 kDa. XPA functions as a DNA-binding protein and is expressed in various tissues including skin cells. XPA recognizes and stabilizes the DNA damage site acting as a scaffold to recruit other repair factors ensuring the proper assembly of essential components in the repair complex.
Biological function summary

The protein is essential for maintaining genomic stability by facilitating the repair of DNA lesions. XPA operates within a multiprotein complex that includes the proteins ERCC1 and XPF. The complex identifies a wide range of structural abnormalities in DNA such as UV-induced photoproducts and chemically induced adducts. Without XPA the NER system's efficiency decreases leaving cells vulnerable to genotoxic stresses causing mutations and damage accumulation.

Pathways

XPA plays a role in the nucleotide excision repair and the base excision repair pathways. These pathways work jointly to ensure the removal of damaged DNA sections and accurate DNA synthesis. Within the NER pathway XPA interacts with proteins like RPA (Replication Protein A) and TFIIH (Transcription Factor IIH) to mediate the excision of damaged oligonucleotides. Its activity is critical for preserving the integrity of the genetic code especially in response to DNA damage caused by external agents like UV radiation.

Mutations or deficiencies in XPA are linked to xeroderma pigmentosum a disorder characterized by extreme sensitivity to ultraviolet light and a heightened risk of skin cancer. This condition results from impaired DNA repair leading to the accumulation of unrepaired DNA damage. XPA also interacts with other NER proteins like ERCC1 and XPF whose dysfunction is implicated in similar DNA repair disorders emphasizing the interconnected nature of these repair pathways in protecting against genotoxic agents.

Target data

Involved in DNA nucleotide excision repair (NER). Initiates repair by binding to damaged sites with various affinities, depending on the photoproduct and the transcriptional state of the region. Required for UV-induced CHEK1 phosphorylation and the recruitment of CEP164 to cyclobutane pyrimidine dimmers (CPD), sites of DNA damage after UV irradiation (PubMed : 19197159). During NER stimulates the 5'-3' helicase activity of XPD/ERCC2 and the DNA translocase activity of XPB/ERCC3 (PubMed : 31253769). Connects XPD/ERCC2 and XPB/ERCC3 during NER, retaining DNA near the XPB/ERCC3 active site, and stabilizing the complex in a different conformation than in transcribing TFIIH (PubMed : 31253769).
