Conjugate Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

Tag Info
The following tags are available.
N-terminal His-tagged
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
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 before Lyophilization
Tris/PBS-based buffer, 6% Trehalose, pH 8.0
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
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Please contact us to get it.

Target Background

Acts as component of the MCM2-7 complex (MCM complex) which is the putative replicative helicase essential for 'once per cell cycle' DNA replication initiation and elongation in eukaryotic cells. The active ATPase sites in the MCM2-7 ring are formed through the interaction surfaces of two neighboring subunits such that a critical structure of a conserved arginine finger motif is provided in trans relative to the ATP-binding site of the Walker A box of the adjacent subunit. The six ATPase active sites, however, are likely to contribute differentially to the complex helicase activity.
Gene References into Functions
  1. MCM4 and MCM7 expression is significantly correlated with Ki-67, Bmi1, and cyclin E expression in esophageal adenocarcinoma, squamous cell carcinoma and precancerous lesions. PMID: 27476776
  2. This MCM4 mutation affected human MCM4/6/7 complex formation, since the complex containing the mutant MCM4 protein is unstable and the mutant MCM4 protein is tend to be degraded. PMID: 27794528
  3. We did not find any evidence of augmented response to a short-term (48 h) cisplatin treatment in these MCM4-deficient cells. However, MCM4-/HPV16+ SiHa cells cannot withstand a prolonged treatment (up to 5 days) of even a sublethal dosage of cisplatin PMID: 26188903
  4. Purified MCM4/6/7 complex containing the G364R MCM4 exhibited similar levels of single-stranded DNA binding and ATPase activities to the complex containing wild-type MCM4 PMID: 25661590
  5. Mutant p53 depletion profoundly influenced PARP1 localization and increased the level of PCNA and MCM4 proteins. PMID: 25733866
  6. Peroxisome proliferator-activated receptor gamma coactivator 1beta (PGC-1beta) protein attenuates vascular lesion formation by inhibition of chromatin loading of minichromosome maintenance complex in smooth muscle cells PMID: 23264620
  7. point mutation of MCM4 perturbs proper interaction with MCM6 to affect complex formation of MCM4/6/7 that is a core structure of MCM2-7 complex PMID: 22668557
  8. Mutations in MCM4/PRKDC represent a novel cause of DNA breakage and NK cell deficiency. PMID: 22499342
  9. Widdrol breaks DNA directly in HT29 cells, resulting in checkpoint activation via Chk2-p53-Cdc25A-p21-MCM4 pathway and finally cells go to G1-phase cell cycle arrest and apoptosis. PMID: 22160829
  10. partial MCM4 deficiency results in a genetic syndrome of growth retardation with adrenal insufficiency and selective NK deficiency PMID: 22354167
  11. MCM4 mutation may have a role in adrenal failure, short stature, and natural killer cell deficiency PMID: 22354170
  12. higher expression in non-small cell lung cancer PMID: 20884074
  13. MCM4 did not predict patient survival in this series of cutaneous melanomas. PMID: 20398247
  14. the phosphorylation of MCM4 in the checkpoint control inhibits DNA replication, which includes blockage of DNA fork progression, through inactivation of the MCM complex PMID: 12714602
  15. HU- or UV irradiation-stimulated phosphorylation of MCM4 at several CDK sites led to inhibition of MCM4 helicase activity, consistent with the notion that the phosphorylation of MCM4 is involved in regulation of DNA synthesis in the checkpoint control. PMID: 15037254
  16. These results suggest that phosphorylation of MCM4 has several distinct and site-specific roles in the function of MCM during the mammalian cell cycle. PMID: 16519687
  17. Expression of EBV-protein kinase caused phosphorylation of Thr-19 & Thr-110 on MCM4 PMID: 17005684
  18. MCM4 phosphorylation by Cdc7 kinase facilitates its interaction with Cdc45 on chromatin PMID: 17046832
  19. The positive rate of MCM4 was significantly higher in stage T3 than in stage T1 esophageal cancer. PMID: 17222376
  20. Data show that two fragments (148-441 and 442-676) from the central region of MCM2 were mainly responsible for the interaction between MCM2 and MCM4, and this was revealed by a pulldown analysis using MCM4 protein beads. PMID: 18190532
  21. Sequence alignment of archaeal MCMs and MCM4 from Homo sapiens and Saccharomyces cerevisiae shows that Aeropyrum pernix MCM shares 32% identity with human and yeast MCM4. PMID: 19053250
