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 (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC         ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.12;
CC   -!- SUBUNIT: Heterodimer of Ku70 and Ku80. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Chromosome, telomere
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the ku70 family. {ECO:0000305}.
