Here we show that exceptionally potent G-quadruplex unwinding is conserved among Pif1 helicases. Moreover, Pif1 helicases from organisms separated by more than 3 billion years of evolution suppressed DNA damage at G-quadruplex motifs in yeast. The G-quadruplex-induced damage generated in the absence of Pif1 helicases led to new genetic and epigenetic changes. Furthermore, when expressed in yeast, human PIF1 suppressed both G-quadruplex-associated DNA damage and telomere lengthening..
