Required for timely CC replication of the telomere and subtelomeric DNA and for wild-type CC levels of telomeric silencing. Involved in DNA repair during stalled CC replication fork, regulation of fragile sites expression and essential CC for genome stability. Plays also a role in mtDNA replication. Has G- CC quadruplex (G4) unwinding activity and can suppress G4-induced genome CC instability when PIF1 levels are low. 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 -!- SUBCELLULAR LOCATION: Nucleus. Chromosome, telomere. CC -!- SIMILARITY: Belongs to the helicase family. PIF1 subfamily.
