特徴

• Single-stranded DNA-dependent ATP-dependent helicase.
• Has a role inchromosome 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 increasingthe 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), bycatalyzing 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.
