Human RECQL5β stimulates flap endonuclease 1
Human RECQL5 is a member of the RecQ helicase family which is implicated in genome maintenance. Five human members of the family have been identified; three of them, BLM, WRN and RECQL4 are associated with elevated cancer risk. RECQL1 and RECQL5 have not been linked to any human disorder yet; cells devoid of RECQL1 and RECQL5 display increased chromosomal instability. Here, we report the physic...

متن کاملHuman Bloom protein stimulates flap endonuclease 1 activity by resolving DNA secondary structure.
Flap endonuclease 1 (FEN1) participates in removal of RNA primers of Okazaki fragments, several DNA repair pathways, and genome stability maintenance. Defects in yeast FEN1 produce chromosomal instability, hyper-recombination, and sequence duplication. These occur because flaps produced during replication are not promptly removed. Long-lived flaps sustain breaks and form misaligned bubble struc...
متن کاملThe human Suv3 helicase interacts with replication protein A and flap endonuclease 1 in the nucleus.
The hSuv3 (human Suv3) helicase has been shown to be a major player in mitochondrial RNA surveillance and decay, but its physiological role might go beyond this functional niche. hSuv3 has been found to interact with BLM (Bloom's syndrome protein) and WRN (Werner's syndrome protein), members of the RecQ helicase family involved in multiple DNA metabolic processes, and in protection and stabiliz...
متن کاملHuman Fanconi Anemia Complementation Group A Protein Stimulates the 5’ Flap Endonuclease Activity of FEN1
In eukaryotic cells, Flap endonuclease 1 (FEN1) is a major structure-specific endonuclease that processes 5' flapped structures during maturation of lagging strand DNA synthesis, long patch base excision repair, and rescue of stalled replication forks. Here we report that fanconi anemia complementation group A protein (FANCA), a protein that recognizes 5' flap structures and is involved in DNA ...
