  • N-terminal region (AAs 1-56) necessary both for protein oligomerization and for this Holliday junction disruption activity
  • seven RecQ helicase domains
  • RecQ-specific zinc-binding domain
  • N-terminal winged-helix (WH) domain, with prominent beta-hairpin essential for DNA strand separation, which may be analogous to DNA strand-separation features of other DNA helicases

    SUBCELLULAR LOCALIZATION     intracellular
  • RECQL and FEN1 were constitutively present at telomeres and their binding to the telomeric chromatin was enhanced following DNA damage
  • basic FUNCTION
  • DNA helicase with DNA dependent ATPase activity, putatively involved in DNA repair and/or chromosome segregation
  • playing a role in the maintenance of genome stability that is distinct from that of BLM
  • playing an important role in preserving genomic integrity, and having cellular roles in DNA repair, recombination, and replication
  • playing a role in a pathway involving mismatch repair factors, and regulation of genetic recombination
  • having a unique cellular role in the DNA repair processes required for genomic integrity
  • catalyzes unidirectional three-stranded branch migration with a 3' --> 5' polarity
  • involved in maintaining chromosome stability
  • RECQL and WRN proteins are RecQ DNA helicases that participate in suppression of DNA hyper-recombination and repair
  • role of RECQL in replication fork stabilization and role in the DNA damage response to maintain genomic stability
  • crucial role for RECQL at naturally occurring fork stalling sites, implicating RECQL in mechanisms underlying common fragile site instability in cancer
  • may participate in the same pathway as WRN, probably in telomere replication
  • novel function of RECQL in gene regulation, indicating that RECQL contributes to tumor development and progression, in part, by regulating the expression of key genes that promote cancer cell migration, invasion and metastasis
  • RECQL helicases and PARP1 are involved in the control of DNA repair, telomere maintenance, and replicative stress
  • CELLULAR PROCESS nucleotide, repair
    a component
    small molecule
  • stimulates the incision activity of human exonuclease 1 (EXO1)
  • the mismatch repair recognition complex MSH2/6 stimulates RECQ1 helicase activity
  • PARP1 stabilizes forks in the regressed state by limiting their restart by RECQL
  • interaction of RECQL with XRCC5/XRCC6 and role of the human RecQ helicase in double-strand break repair through nonhomologous end-joining
  • cooperative function of RECQLs and PARP1 represents an important factor for maintaining genome integrity
  • RECQL limits DNA2 activity by preventing extensive nascent strand degradation
  • conserved collaboration of RECQL with FEN1, suggesting both overlapping and specialized roles of RECQL in the processing of DNA structure intermediates proposed to arise during replication, repair and recombination
