Gene RIF (19)

25909997 BRCA1 and CtIP contribute to DSB resection by recruiting Dna2 to damage sites, thus ensuring the robust DSB resection necessary for efficient homologous recombination.
25733713 EXO1, MRE11, and CtIP are not involved in the same mechanism of reversed fork processing, whereas human RECQ1 limits DNA2 activity by preventing extensive nascent strand degradation.
25238049 depletion of DNA2 in cells reduces proliferation, addition of estrogen restores proliferation. cells responding to estrogen will proliferate despite impaired in DNA2 activity, potentially promoting genomic instability and triggering cancer development.
25200081 DNA2 stimulates the helicase activity of BLM.
25122754 WRN and BLM act epistatically with DNA2 to promote the long-range resection of double strand break ends in human cells.
24626199 The suppression of FANCD2(-/-) by DNA2 knockdowns suggests that DNA2 and FANCD2 also have antagonistic roles: in the absence of FANCD2, DNA2 somehow corrupts repair.
23352259 These results implicate human DNA2 and the long-patch base-excision repair pathway in the pathogenesis of adult-onset disorders of mtDNA maintenance.
22987153 DNA2 interacts with FANCD2, and cisplatin induces FANCD2 ubiquitylation even in the absence of DNA2.

20131965 reviews the evidence for the dynamic design of Okazaki fragment processing and the roles of Dna2 and its interacting partners in carrying out this design. [REVIEW]
20019387 Acetylation of Dna2 endonuclease/helicase and flap endonuclease 1 by p300 promotes DNA stability by creating long flap intermediates.
19487465 Data indicate that hDna2 is similar to its yeast counterpart and is a new addition to the growing list of proteins that participate in both nuclear and mitochondrial DNA maintenance.
18995831 studies illustrate an evolutionarily diversified role of hDNA2 in mitochondrial DNA replication and repair in a mammalian system.
18593712 Replication protein A stimulates the 5'- to 3'-nuclease activity of Dna2 and inhibits the 3'- to 5'-exo/endonuclease activity of Dna2.
17032657 report here two novel activities of both the yeast and human Dna2 helicase/nuclease protein: single strand annealing and ATP-independent strand exchange on short duplexes
16595800 hDna2 showed ATPase/helicase activity and 5'-3' exo-endonuclease as well as 3'-5' exo-endonuclease activity, indicating that its biochemical properties are very similar to yeast DNA2.
16595799 The purified human Dna2 enzyme contains intrinsic endonuclease and DNA-dependent ATPase activities, but is devoid of detectable DNA helicase activity.
