|Function||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.|

The protein encoded by this gene is the 80-kilodaltonsubunit of the Ku heterodimer protein which is also known asATP-dependant DNA helicase II or DNA repair protein XRCC5. Ku isthe DNA-binding component of the DNA-dependent protein kinase, andit functions together with the DNA ligase IV-XRCC4 complex in therepair of DNA double-strand break by non-homologous end joining andthe completion of V(D)J recombination events. This genefunctionally complements Chinese hamster xrs-6, a mutant defectivein DNA double-strand break repair and in ability to undergo V(D)Jrecombination. A rare microsatellite polymorphism in this gene isassociated with cancer in patients of varying radiosensitivity.
