Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
緩沖液：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
復(fù)溶：

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
儲(chǔ)存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質(zhì)期：

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
貨期：

Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
注意事項(xiàng)：

Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

靶點(diǎn)詳情

功能：

Key enzyme involved in DNA replication and DNA repair in nucleus and mitochondrion. Involved in Okazaki fragments processing by cleaving long flaps that escape FEN1: flaps that are longer than 27 nucleotides are coated by replication protein A complex (RPA), leading to recruit DNA2 which cleaves the flap until it is too short to bind RPA and becomes a substrate for FEN1. Also involved in 5'-end resection of DNA during double-strand break (DSB) repair: recruited by BLM and mediates the cleavage of 5'-ssDNA, while the 3'-ssDNA cleavage is prevented by the presence of RPA. Also involved in DNA replication checkpoint independently of Okazaki fragments processing. Possesses different enzymatic activities, such as single-stranded DNA (ssDNA)-dependent ATPase, 5'-3' helicase and endonuclease activities. While the ATPase and endonuclease activities are well-defined and play a key role in Okazaki fragments processing and DSB repair, the 5'-3' DNA helicase activity is subject to debate. According to various reports, the helicase activity is weak and its function remains largely unclear. Helicase activity may promote the motion of DNA2 on the flap, helping the nuclease function.

1. This review mainly encompasses the key functions of DNA2 in human cells with various aspects, especially focusing on the genome integrity, and also generalizes the recent insights to the mechanisms related to the occurrence of cancer and other diseases potentially linked to the mutations in DNA2. PMID: 28903076
2. The authors show that the helicase of hDNA2 functionally integrates with BLM or WRN helicases to promote double-stranded DNA degradation by forming a heterodimeric molecular machine. This collectively suggests that the human DNA2 motor promotes the enzyme's capacity to degrade double-stranded DNA in conjunction with BLM or WRN and thus promote the repair of broken DNA. PMID: 27612385
3. the motor of DNA2 functions as a ssDNA translocase to promote degradation of 5'-terminated DNA. PMID: 28336515
4. 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. PMID: 24626199
5. BRCA1 and CtIP contribute to DSB resection by recruiting Dna2 to damage sites, thus ensuring the robust DSB resection necessary for efficient homologous recombination. PMID: 25909997
6. 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. PMID: 25238049
7. 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. PMID: 25733713
8. DNA2 stimulates the helicase activity of BLM. PMID: 25200081
9. WRN and BLM act epistatically with DNA2 to promote the long-range resection of double strand break ends in human cells. PMID: 25122754
10. DNA2 interacts with FANCD2, and cisplatin induces FANCD2 ubiquitylation even in the absence of DNA2. PMID: 22987153

15. Acetylation of Dna2 endonuclease/helicase and flap endonuclease 1 by p300 promotes DNA stability by creating long flap intermediates. PMID: 20019387
16. The purified human Dna2 enzyme contains intrinsic endonuclease and DNA-dependent ATPase activities, but is devoid of detectable DNA helicase activity. PMID: 16595799
17. 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. PMID: 16595800
18. 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 PMID: 17032657
19. Replication protein A stimulates the 5'- to 3'-nuclease activity of Dna2 and inhibits the 3'- to 5'-exo/endonuclease activity of Dna2. PMID: 18593712
20. studies illustrate an evolutionarily diversified role of hDNA2 in mitochondrial DNA replication and repair in a mammalian system. PMID: 18995831
21. 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. PMID: 19487465
