The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application notesIHC-P: 1/100 - 1/500. Epitope exposure is recommended. Epitope exposure with citrate buffer will enhance staining.
Likely to work with frozen sections.
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
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 modificationsPhosphorylated upon DNA damage, probably by ATM or ATR. Ubiquitinated by HERC2 leading to degradation by the proteasome.
