CC -!- FUNCTION: Single-stranded DNA-dependent ATP-dependent helicase.
CC Involved in non-homologous end joining (NHEJ) DNA double strand break
CC repair. DNA-binding is sequence-independent but has a high affinity to
CC nicks in double-stranded DNA and to the ends of duplex DNA. Binds to
CC naturally occurring chromosomal ends, and therefore provides
CC chromosomal end protection. Required also for telomere recombination to
CC repair telomeric ends in the absence of telomerase. KU70, of the
CC KU70/KU80 heterodimer, binds to the stem loop of TLC1, the RNA
CC component of telomerase. Involved in telomere maintenance. Interacts
CC with telomeric repeats and subtelomeric sequences thereby controlling
CC telomere length and protecting against subtelomeric rearrangement.
CC Maintains telomeric chromatin, which is involved in silencing the
CC expression of genes located at the telomere. Required for mating-type
CC switching. {ECO:0000256|ARBA:ARBA00024890}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,

CC Evidence={ECO:0000256|ARBA:ARBA00001665,
CC ECO:0000256|PIRNR:PIRNR016570};
CC -!- SUBUNIT: Heterodimer of Ku70 and Ku80. {ECO:0000256|ARBA:ARBA00011584}.
CC -!- SUBCELLULAR LOCATION: Chromosome, telomere
CC {ECO:0000256|ARBA:ARBA00004574}. Nucleus
CC {ECO:0000256|ARBA:ARBA00004123, ECO:0000256|PIRNR:PIRNR016570}.
