XRCC4 is a repair protein involved in non-homologous end joining (NHEJ) for double-strand DNA break repairs and V(D)J recombination. Wanotayan et al. found that the C-terminal of the XRC4 is conserved amongst vertebrates and found that a functional deficient mutation N326L caused mislocalization of the protein to the cytosol. This can be reversed by LMB treatment. This N326L mutation generated a synthetic NES, where residues 318-326 matches class 2 NES consensus. All other N326 mutants tested and the wild type protein did not have nuclear export activity.

Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus.
Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb
by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
