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
Tag type will be determined during the manufacturing process.
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
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
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
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 Background

Function
Probable actin-based motor with a protein kinase activity. Probably plays a role in vision and hearing. Required for normal cochlear hair bundle development and hearing. Plays an important role in the early steps of cochlear hair bundle morphogenesis. Influences the number and lengths of stereocilia to be produced and limits the growth of microvilli within the forming auditory hair bundles thereby contributing to the architecture of the hair bundle, including its staircase pattern. Involved in the elongation of actin in stereocilia tips by transporting the actin regulatory factor ESPN to the plus ends of actin filaments.
Gene References into Functions
  1. MYO3A is more efficient than MYO3B at increasing formation and elongation of stable microvilli on the surface of cultured epithelial cells. PMID: 27582493
  2. The structures of Myo3 in complex with Espin1 not only elucidate the mechanism of the binding, but also reveal a Myo3-induced release of Espin1 auto-inhibition mechanism. PMID: 26785147
  3. Study reports an amino acid substitution in MYO3A motor-head domain disrupting its ATPase activity that can cause autosomal dominant progressive hereditary hearing loss. Also, these results uncovered a novel interaction between MYO3A and PCDH15 shedding new light on the function of myosin IIIA at stereocilia tips. PMID: 26841241
  4. A homozygous mutation, MYO3A:c.1841C>T (p.S614F), was identified to be responsible for non-syndromic congenital deafness in two members of a Kazakh family in China. PMID: 27063751
  5. Data suggest that, in enterocytes, MYO3A autophosphorylation of kinase domain at Thr184/Thr188 regulates kinase activity, translocation of MYO3A to tips of microvilli, and stability of actin cytoskeleton. PMID: 25402663
  6. The differential regulation of the kinase and motor activities allows for MYO3A to precisely self-regulate its concentration in the actin bundle-based structures of cells. PMID: 24214986
  7. Results suggest that Myo3A motor activity is regulated through a mechanism involving concentration-dependent autophosphorylation. PMID: 20826793
  8. behavioral inhibition-associated SNPs appear to be associated with differences in MYO3A- but not GAD2 lymphoblastoid-mRNA expression levels PMID: 19229853
  9. mutation in humans causes progressive nonsyndromic hearing loss DFNB30 PMID: 12032315
  10. class III myosin is an actin-based motor protein having a protein kinase activity PMID: 12672820
  11. myosin IIIA can spend a majority of its ATP hydrolysis cycling time on actin PMID: 17012748
  12. the actomyosin-ADP state may be important for the ability of myosin III to function as a cellular transporter and actin cross-linker in the actin bundles of sensory cells PMID: 17074769
  13. A model in which the activity and concentration of myosin IIIA localized to the tips of actin bundles mediates the morphology of the tips in sensory cells. PMID: 18229949
