Form
Liquid or Lyophilized powder
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.
Buffer
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, pH 8.0.
Reconstitution
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.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
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.
Lead Time
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
Multifunctional ATP-dependent helicase that unwinds G-quadruplex (G4) structures. Plays a role in many biological processes such as genomic integrity, gene expression regulations and as a sensor to initiate antiviral responses. G4 structures correspond to helical structures containing guanine tetrads. Binds with high affinity to and unwinds G4 structures that are formed in nucleic acids (G4-ADN and G4-RNA). Plays a role in genomic integrity. Converts the G4-RNA structure present in telomerase RNA template component (TREC) into a double-stranded RNA to promote P1 helix formation that acts as a template boundary ensuring accurate reverse transcription. Plays a role in transcriptional regulation. Resolves G4-DNA structures in promoters of genes, such as YY1, KIT/c-kit and ALPL and positively regulates their expression. Plays a role in post-transcriptional regulation. Unwinds a G4-RNA structure located in the 3'-UTR polyadenylation site of the pre-mRNA TP53 and stimulates TP53 pre-mRNA 3'-end processing in response to ultraviolet (UV)-induced DNA damage. Binds to the precursor-microRNA-134 (pre-miR-134) terminal loop and regulates its transport into the synapto-dendritic compartment. Involved in the pre-miR-134-dependent inhibition of target gene expression and the control of dendritic spine size. Plays a role in the regulation of cytoplasmic mRNA translation and mRNA stability. Binds to both G4-RNA structures and alternative non-quadruplex-forming sequence within the 3'-UTR of the PITX1 mRNA regulating negatively PITX1 protein expression. Binds to both G4-RNA structure in the 5'-UTR and AU-rich elements (AREs) localized in the 3'-UTR of NKX2-5 mRNA to either stimulate protein translation or induce mRNA decay in an ELAVL1-dependent manner, respectively. Binds also to ARE sequences present in several mRNAs mediating exosome-mediated 3'-5' mRNA degradation. Involved in cytoplasmic urokinase-type plasminogen activator (uPA) mRNA decay. Component of a multi-helicase-TICAM1 complex that acts as a cytoplasmic sensor of viral double-stranded RNA (dsRNA) and plays a role in the activation of a cascade of antiviral responses including the induction of proinflammatory cytokines via the adapter molecule TICAM1. Required for early embryonic development and hematopoiesis. Involved in the regulation of cardioblast differentiation and proliferation during heart development. Involved in spermatogonia differentiation. May play a role in ossification.

  1. Data show that helicases RHAU, BLM, and WRN exhibit distinct G-quadruplex (GQ) conformation specificity, but use a common mechanism of repetitive unfolding that leads to disrupting GQ structure multiple times in succession. PMID: 27407146
  2. RHAU mediates the unfolding of DNA and RNA quadruplexes. PMID: 28065761
  3. The study provides the first evidence that the unfolding kinetics of a G-quadruplex can be modulated by different nucleotide-bound states of the RHAU helicase. PMID: 28069994
  4. RHAU binds to an adenosine-rich region near the 3'-end of the long non-coding RNA BC200. PMID: 26740632

  7. Used an integrated approach that includes small angle x-ray scattering, nuclear magnetic resonance spectroscopy, circular dichroism, and dynamic light scattering methods to demonstrate the recognition of G-quadruplexes by the N-terminal domain of RHAU. PMID: 24151078
  8. Data supports a helicase function of RHAU on an intramolecular RNA quadruplex and show that the enzyme is capable of completely converting quadruplex RNA to a stable duplex. PMID: 22238380
  9. Data show that hnRNPA1/A2, HuR and DAZAP1 splicing factors and DHX36 RNA helicase bind to the ISE, with hnRNPA1 acting negatively and DAZAP1 positively on splicing selection PMID: 21858080
  10. The helicase domain of DHX36 does not mediate telomerase RNA (hTR) binding; instead, hTR interacts with the N-terminal accessory domain of DHX36 known to bind specifically to the parallel-strand G-quadruplex substrates resolved by the helicase domain. PMID: 21149580
  11. The amino-terminal region of RHAU is essential for RHAU to bind G4 structures and within this region the evolutionary conserved RSM (RHAU-specific motif) domain is a major affinity and specificity determinant PMID: 20472641
  12. DHX9/DHX36 represent the MyD88-dependent DNA sensors in the cytosol of plasmacytoid dendritic cells and suggest a much broader role for DHX helicases in viral sensing PMID: 20696886
  13. DHX36 protein is responsible for the majority of tetramolecular G4-DNA resolvase activity PMID: 16150737
  14. RHAU has a dual function, being involved in both the synthesis and degradation of mRNA in different subcellular compartments. PMID: 18279852
