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.
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°C/-80°C. 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.

Target Background

Function
Isoform beta is a DNA helicase that plays an important role in DNA replication, transcription and repair. Inhibits elongation of stalled transcripts at DNA damage sites by binding to the RNA polymerase II subunit POLR2A and blocking the TCEA1 binding site. Required for mitotic chromosome separation after cross-over events and cell cycle progress. Required for efficient DNA repair, including repair of inter-strand cross-links. Stimulates DNA decatenation mediated by TOP2A. Prevents sister chromatid exchange and homologous recombination.
Gene References into Functions
  1. It has been shown that conjugation of SUMO2, but not SUMO1 or SUMO3, to the essential replication factor PCNA is induced on transcribed chromatin by the RNAPII-bound helicase RECQ5. PMID: 30006506
  2. we have shown that increased expression of RECQL5 protein occurs and is likely to contribute to tumourigenesis in UCC and that the pharmacological targeting of the helicase activity of RECQL5 is a strong target for future small molecule inhibitor development. PMID: 27764811
  3. RECQ5 removes RAD51 filaments stabilizing stalled replication forks at common fragile sites and hence facilitates CFS cleavage by MUS81-EME1. PMID: 28575661
  4. the open and closed forms of RECQL5 were used together with a quantitative comparison of all current RecQ family structures to construct a mechanistic model for RECQL5 helicase activity PMID: 28100692
  5. Study characterized the G-quadruplex (GQ) unfolding activity of RECQ5 for different DNA constructs under different salt conditions, showed that RECQ5 is overall a weak GQ destabilizer compared to Bloom and Werner PMID: 27332117
  6. interaction between RECQ5 and proliferating cell nuclear antigen (PCNA) promotes RAD18-dependent PCNA ubiquitination and the helicase activity of RECQ5 promotes the processing of replication intermediates. PMID: 27502483
  7. RECQL5 has unique strand annealing properties relative to the other human RecQ helicase proteins PMID: 26717024
  8. RECQL5 is a critical regulator of genome stability in myeloproliferative neoplasms and demonstrate that replication stress-associated cytotoxicity can be amplified specifically in JAK2V617F mutant cells through RECQL5-targeted synthetic lethality. PMID: 26686625
  9. mutation associated with early myocardial infarction PMID: 26844521
  10. Expression of RECQL5 in breast cancer can drive proliferation supporting an oncogenic function for RECQL5 in breast cancer. RECQL5 is a promising biomarker in breast cancer. PMID: 26586793
  11. RecQ5 prevents transcription associated genome instability by facilitating PIAS1-SRSF1 ligase complex sumoylation of DNA topoisomerase 1. PMID: 25851487
  12. results suggested RECQL5 as a tumor suppressor in osteosarcoma and may be a potential therapeutic target for osteosarcoma treatment PMID: 26499077
  13. The RECQL5 genetic polymorphism was associated with osteosarcoma in a Chinese population. PMID: 25867335

  15. RECQL5 as a major determinant for camptothecin resistance in colorectal cancer cells. PMID: 21210765
  16. The data presented here provide evidence that RECQL5 plays a general role in the control of transcript elongation in human cells. In its absence, transcript elongation rates increase, the distribution profile of RNAPII is markedly altered across the genome, and higher levels of RNAPII pausing or arrest (i.e., transcription stress) are detected. PMID: 24836610
  17. RECQL5 genetic polymorphisms were associated with osteosarcoma in a Chinese population. PMID: 24287950

  19. The findings suggest that RECQ5 acts during the post-synaptic phase of synthesis-dependent strand annealing to prevent formation of aberrant RAD51 filaments on the extended invading strand, thus limiting its channeling into potentially hazardous crossover pathway of homologous recombination. PMID: 24319145
  20. This article reviews the established roles of RECQL5 at the cross roads of DNA replication, recombination and transcription, and propose that human RECQL5 provides important backup functions in the absence of other DNA helicases.[review] PMID: 23627586
  21. RECQL5 contacts the Rpb1 jaw domain of Pol II at a site that overlaps with the binding site for the transcription elongation factor TFIIS. Binding of RECQL5 to Pol II interferes with the ability of TFIIS to promote transcriptional read-through in vitro. PMID: 23748380
