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.
Form Lyophilized powder
Buffer before Lyophilization 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.

Protein FAQs
Storage Condition Store at -20°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.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Data

Function Plus-end tracking protein (+TIP) that binds to the plus-end of microtubules and regulates the dynamics of the microtubule cytoskeleton. Promotes microtubule growth. May be involved in spindle function by stabilizing microtubules and anchoring them at centrosomes. Also acts as a regulator of minus-end microtubule organization
Gene References into Functions
  1. One candidate pathway coupling actin filaments to microtubules consists of the actin filament-binding protein drebrin and the microtubule-binding +TIP protein EB3. This pathway is regulated proximally by cyclin-dependent kinase 5 phosphorylation of drebrin but the upstream elements in the pathway have yet to be identified. PMID: 28865014
  2. Findings show that co-ordination of dynamic microtubules and actin filaments by the drebrin/EB3 pathway drives prostate cancer cell invasion and is therefore implicated in disease progression. PMID: 28319065
  3. Findings suggest that methylation-associated down-regulation of EBF3 and IRX1 genes may play an important role in a pathogenic effect of TGF-beta on RASFs. PMID: 23456299
  4. Daughter cell adhesion and cytokinesis completion are spatially regulated by distinct states of EB3 phosphorylation on serine 176 by Aurora B. PMID: 23712260
  5. decreasing the drebrin E levels disrupted the normal subapical F-actin-myosin-IIB-betaII-spectrin network and the apical accumulation of EB3, a microtubule-plus-end-binding protein PMID: 22275434
  6. VE-cadherin outside-in signaling regulates cytosolic calcium homeostasis and EB3 phosphorylation. PMID: 23159740
  7. study found a polycytosine repeat (C8) in exon 5 of MAPRE3 that could be a potential mutation target in cancers with microsatellite instability (MSI); found that the C8 is frequently mutated in gastric and colorectal carcinomas with MSI PMID: 20632835
  8. The RP3 protein is involved in SATB1-mediated gene repression of Bcl2 and dynein subunit rp3 has functions independent of the dynein motor. PMID: 16079286
  9. Data show that two mitotic kinases, Aurora-A and Aurora-B, phosphorylate endogenous EB3 at Ser-176, and the phosphorylation triggers disruption of the EB3-SIAH-1 complex, resulting in EB3 stabilization during mitosis. PMID: 19696028
