-[[https://www.uniprot.org/uniprot/XRCC5_HUMAN XRCC5_HUMAN]] Single stranded DNA-dependent ATP-dependent helicase. Has a role in chromosome translocation. The DNA helicase II complex binds preferentially to fork-like ends of double-stranded DNA in a cell cycle-dependent manner. It works in the 3'-5' direction. Binding to DNA may be mediated by XRCC6. Involved in DNA non-homologous end joining (NHEJ) required for double-strand break repair and V(D)J recombination. The XRCC5/6 dimer acts as regulatory subunit of the DNA-dependent protein kinase complex DNA-PK by increasing the affinity of the catalytic subunit PRKDC to DNA by 100-fold. The XRCC5/6 dimer is probably involved in stabilizing broken DNA ends and bringing them together. The assembly of the DNA-PK complex to DNA ends is required for the NHEJ ligation step. In association with NAA15, the XRCC5/6 dimer binds to the osteocalcin promoter and activates osteocalcin expression. The XRCC5/6 dimer probably also acts as a 5'-deoxyribose-5-phosphate lyase (5'-dRP lyase), by catalyzing the beta-elimination of the 5' deoxyribose-5-phosphate at an abasic site near double-strand breaks. XRCC5 probably acts as the catalytic subunit of 5'-dRP activity, and allows to 'clean' the termini of abasic sites, a class of nucleotide damage commonly associated with strand breaks, before such broken ends can be joined. The XRCC5/6 dimer together with APEX1 acts as a negative regulator of transcription.<ref>PMID:7957065</ref> <ref>PMID:8621488</ref> <ref>PMID:12145306</ref> <ref>PMID:20383123</ref>

-== Publication Abstract from PubMed ==
-The solution structure of Ku80 CTD from residue 566 to 732 has been solved in order to gain insights into the mechanisms of its interactions with other proteins. The structure reveals a topology similar to several common scaffolds for protein-protein interactions, in the absence of significant sequence similarity to these proteins. Conserved surface amino acid residues are clustered on two main surface areas, which are likely involved in mediating interactions between Ku80 and other proteins. The Ku70/Ku80 heterodimer has been shown to be involved in at least three processes, nonhomologous end joining, transcription, and telomere maintenance, and thus it needs to interact with different proteins involved in these different processes. The three-dimensional structure of the Ku80 C-terminal domain and the availability of NMR chemical shift assignments provide a basis for further investigation of the interactions between Ku80 and other proteins in these Ku-dependent cellular functions.
