Human XPA knockout HeLa cell pellet -
Product overview
Abcam’s knockout cell pellets give you access to native proteins, without the need to culture cells. Our knockout cell pellets are prepared from our single-gene knockout cell lines and provide an additional offering to our cell lysates.
Cells are snap-frozen to provide high quality pellets that are suitable for extraction with alternative lysis buffers or for preparation of lysates from subcellular fractions. Our knockout cell pellets are suitable for a variety of applications, including PCR, gene expression profiling and DNA library preparation. -

Function
Involved 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 specificity
Expressed in various cell lines and in skin fibroblasts. -
Involvement in disease
Defects 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 similarities
Belongs to the XPA family. -
Post-translational
modificationsPhosphorylated upon DNA damage, probably by ATM or ATR.
Ubiquitinated by HERC2 leading to degradation by the proteasome. -
Cellular localization
Nucleus. - Information by UniProt

Western blot - Human XPA knockout HeLa cell pellet (ab279027)
Lane 1: Wild-type HeLa cell lysate (20 µg)
Lane 2: XPA knockout HeLa cell lysate (20 µg)
Lane 3: 293T cell lysate (20 µg)
Lanes 1-3: Merged signal (red and green). Green - ab65963 observed at 38 kDa. Red - loading control, ab52866 observed at 50 kDa.
ab65963 Anti-XPA antibody [5F12] was shown to specifically react with XPA in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab264663 (knockout cell lysate ab258764) was used. Wild-type and XPA knockout samples were subjected to SDS-PAGE. ab65963 and Anti-alpha Tubulin antibody [EP1332Y] - Loading Control (ab52866) were incubated overnight at 4°C at 1 in 500 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preadsorbed (ab216772) and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preadsorbed (ab216777) secondary antibodies at 1 in 10000 dilution for 1 hour at room temperature before imaging.
