Target Background

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 ends. Releases telomerase by unwinding the short telomerase RNA/telomeric DNA hybrid that is the intermediate in the telomerase reaction. Possesses an intrinsic strand annealing activity.
Gene References into Functions
  1. Structural and functional characterization of the unwinding mechanism of Bacteroides and human Pif1 helicases has been reported. PMID: 26904952
  2. Authors characterised a functional role for human PIF1 in DNA replication that becomes important for cell growth under oncogenic stress. PMID: 25359767
  3. Pif1 readily unfolds a parallel quadruplex DNA substrate in a multiturnover reaction and also generates some product under single cycle conditions PMID: 25589786
  4. A minimum of 10 oligonucleotide bases are required for PIF1 binding and the hydrolysis of ATP. PMID: 23924759
  5. the yeast ortholog of Pif1 appears to move along DNA in single nucleotide or base pair steps, powered by hydrolysis of 1 molecule of ATP. PMID: 23596008
  6. Evidence that the PIF1 N-terminal (PINT) domain as crucial functions in PIF1 helicase. PMID: 18835853
  7. when expressed in yeast, human PIF1 suppressed both G-quadruplex-associated DNA damage and telomere lengthening PMID: 23657261
  8. PIF1 variant L319P was identified in three breast cancer families PMID: 22347400
  9. Findings suggest roles for PIF1 in S-phase entry and progression that are essential to protect human tumor cells from apoptosis. PMID: 21616935
  10. Human Pif1 could have a role in processing G4 structures that arise in the single-stranded nucleic acid intermediates formed during DNA replication and gene expression. PMID: 20524933
  11. hPif1 may regulate telomere elongation by decreasing telomerase processivity, possibly via a mechanism that involves the unwinding of telomerase RNA from telomeric DNA by hPif1. PMID: 16522649
  12. Human PIF, like S. cerevisiae Pif1p, plays a role in telomerase regulation. PMID: 17172855
  13. hPif1 in the nucleus may be involved in chromosome maintenance in association with DNA replication PMID: 17827721
  14. hPif1 specifically recognizes and unwinds DNA structures resembling putative stalled replication forks. PMID: 19700773
