(A) Pif1–PCNA interaction is important for replication through G4 structures. Replication time of 30 Kb through G4(A+B) located on the lagging strand in strains with pif1-R3Emut (n = 26)(18), pif1-PIPmut (n = 25) shown in blue and pif1-m2 (n = 26) in comparison to WT, pif1Δ (Figure 2C). Significance was determined by Monte Carlo resampling *P< 0.05, **P< 0.005. Error bars are ± SEM. (B) DNA primer extension activity of Pol δ past G4(B) in the presence of the Δ237Pif1 wild-type or its Pif1-PIPmut variant containing the F760A Y761A mutations. Standard deviations are from five independent experiments.
