  • FunctionInvolved in DNA excision repair. 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 CHK1 phosphorylation and the recruitment of CEP164 to cyclobutane pyrimidine dimmers (CPD), sites of DNA damage after UV irradiation.
  • Tissue specificityExpressed in various cell lines and in skin fibroblasts.
  • Involvement in diseaseDefects in XPA are a cause of xeroderma pigmentosum complementation group A (XP-A) [MIM:278700]; also known as xeroderma pigmentosum type 1 (XP1). XP-A is a rare human autosomal recessive disease characterized by solar sensitivity, high predisposition for developing cancers on areas exposed to sunlight and, in some cases, neurological abnormalities. Group A patients show the most severe skin symptoms and progressive neurological disorders.
  • Sequence similaritiesBelongs to the XPA family.
  • Post-translational
    Phosphorylated upon DNA damage, probably by ATM or ATR.
    Ubiquitinated by HERC2 leading to degradation by the proteasome.
