PIF1 | ATP-dependent DNA helicase PIF1; DNA-dependent ATPase and 5'-3' DNA helicase required for the maintenance of both mitochondrial and nuclear genome stability. Efficiently unwinds G-quadruplex (G4) DNA structures and forked RNA-DNA hybrids. Resolves G4 structures, preventing replication pausing and double-strand breaks (DSBs) at G4 motifs. Involved in the maintenance of telomeric DNA. Inhibits telomere elongation, de novo telomere formation and telomere addition to DSBs via catalytic inhibition of telomerase. Reduces the processivity of telomerase by displacing active telomerase from DNA [...] (906 aa) | ||||

SGS1 | ATP-dependent DNA helicase. (1189 aa) | ||||
EST3 | Telomere replication protein EST3; Component of the telomerase complex involved in telomere replication. Stimulates RNA/DNA heteroduplex unwinding which favors the telomere replication by the telomerase (By similarity). (210 aa) |
