25589786 Pif1 readily unfolds a parallel quadruplex DNA substrate in a multiturnover reaction and also generates some product under single cycle conditions
25359767 Authors characterised a functional role for human PIF1 in DNA replication that becomes important for cell growth under oncogenic stress.
23924759 A minimum of 10 oligonucleotide bases are required for PIF1 binding and the hydrolysis of ATP.
23657261 when expressed in yeast, human PIF1 suppressed both G-quadruplex-associated DNA damage and telomere lengthening
23596008 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.
22347400 PIF1 variant L319P was identified in three breast cancer families
21616935 Findings suggest roles for PIF1 in S-phase entry and progression that are essential to protect human tumor cells from apoptosis.
20524933 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.
19700773 hPif1 specifically recognizes and unwinds DNA structures resembling putative stalled replication forks.
18835853 Evidence that the PIF1 N-terminal (PINT) domain as crucial functions in PIF1 helicase.
17827721 hPif1 in the nucleus may be involved in chromosome maintenance in association with DNA replication
17172855 Human PIF, like S. cerevisiae Pif1p, plays a role in telomerase regulation.
16522649 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.
