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
Myosins are actin-based motor molecules with ATPase activity. Unconventional myosins serve in intracellular movements. Their highly divergent tails are presumed to bind to membranous compartments, which would be moved relative to actin filaments. Required for the arrangement of stereocilia in mature hair bundles.
Gene References into Functions
  1. Gpsm2 defines an approximately 200 nm nanodomain at the tips of stereocilia and this localization requires the presence of Galphai3, myosin 15 and whirlin. PMID: 28387217
  2. Myosin 15 isoforms can navigate between functionally distinct classes of stereocilia, and are independently required to assemble and then maintain the intricate hair bundle architecture. PMID: 26302205
  3. myo15-subfragment 1 is a barbed-end-directed motor that moves actin filaments in a gliding assay using a power stroke of 7.9 nm. Myo15-S1 was rate limited by transit through strongly actin-bound states, similar to other processive myosin motors. PMID: 25114250
  4. Genetic association between myoXV and deafness in a murine model. PMID: 22949591
  5. It was concluded that MyoXVa, whirlin, and Eps8 are integral components of the stereocilia tip complex, where Eps8 is a central actin-regulatory element for elongation of the stereocilia actin core. PMID: 21236676
  6. endogenous myosin XVa localizes to the tips of the stereocilia of the cochlear and vestibular hair cells PMID: 14610277
  7. myosin-XVa is a motor protein that, in vivo, interacts with the third PDZ domain of whirlin through its carboxy-terminal PDZ-ligand. Myosin-XVa then delivers whirlin to the tips of stereocilia. PMID: 15654330
  8. This comparison revealed that the absence of functional myosin-XVa does not disrupt adaptation of the mechanotransduction current during sustained bundle deflection. PMID: 16973713
  9. The morphology of cochlear hair cell stereocilia in double mutants reflects a dominance of the more severe Myo15 (sh2/sh2) phenotype over the Whrn (wi/wi) phenotype. PMID: 17619105
  10. The Ca(2+) sensitivity of the mechanotransduction channels and the fast adaptation require a structural environment that is dependent on myosin-XVa and is disrupted in Myo15(sh2/sh2) inner hair cells, but not in Myo15(sh2/sh2) outer hair cells. PMID: 19339598

Involvement in disease
Defects in Myo15a are the cause of shaker-2 (sh-2), a condition causing deafness, circling behavior, head tossing and hyperactivity. Auditory hair cells of affected animals have very short stereocilia and a long actin-containing protrusion at their basal end.
Subcellular Location
Cell projection, stereocilium. Cytoplasm, cytoskeleton. Note=Localizes to stereocilium tips in cochlear and vestibular hair cells.
Protein Families
TRAFAC class myosin-kinesin ATPase superfamily, Myosin family
Tissue Specificity
In the developing inner ear, expressed in cochlea and vestibular apparatus. Expression appears to be restricted to cochlear neurosensory cells and upper epithelial layer of macula saccula. Also expressed in macula utriculi and cristae ampullaris of the se
