Function
Structure-specific DNA repair endonuclease responsible for the 5-prime incision during DNA repair. Involved in homologous recombination that assists in removing interstrand cross-link. -
Involvement in disease
Defects in ERCC4 are the cause of xeroderma pigmentosum complementation group F (XP-F) [MIM:278760]; also known as xeroderma pigmentosum VI (XP6). XP-F is an autosomal recessive disease characterized by hypersensitivity of the skin to sunlight followed by high incidence of skin cancer and frequent neurologic abnormalities.
Defects in ERCC4 are a cause of XFE progeroid syndrome (XFEPS) [MIM:610965]. This syndrome is illustrated by one patient who presented with dwarfism, cachexia and microcephaly. -

Predicted band size: 103 kDa
Observed band size: 105 kDa why is the actual band size different from the predicted?False colour image of Western blot: Anti-XPF antibody staining at 1/2000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab76948 was shown to bind specifically to XPF. A band was observed at 105 kDa in wild-type HeLa cell lysates with no signal observed at this size in ercc4 knockout cell line ab280068 (knockout cell lysate ab280127). To generate this image, wild-type and ercc4 knockout HeLa cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 5% milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4°C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) at 1/20000 dilution.
