    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.

    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.
  • 产品提供形式：
    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.
  • 复溶：
    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.
  • 储存条件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.

  • 功能：
    Dynamin-related GTPase that is essential for normal mitochondrial morphology by regulating the equilibrium between mitochondrial fusion and mitochondrial fission. Coexpression of isoform 1 with shorter alternative products is required for optimal activity in promoting mitochondrial fusion. Binds lipid membranes enriched in negatively charged phospholipids, such as cardiolipin, and promotes membrane tubulation. The intrinsic GTPase activity is low, and is strongly increased by interaction with lipid membranes. Plays a role in remodeling cristae and the release of cytochrome c during apoptosis. Proteolytic processing in response to intrinsic apoptotic signals may lead to disassembly of OPA1 oligomers and release of the caspase activator cytochrome C (CYCS) into the mitochondrial intermembrane space. Plays a role in mitochondrial genome maintenance.; Inactive form produced by cleavage at S1 position by OMA1 following stress conditions that induce loss of mitochondrial membrane potential, leading to negative regulation of mitochondrial fusion.; Isoforms that contain the alternative exon 4b (present in isoform 2 and isoform 3, but not in isoform 1) are required for mitochondrial genome maintenance, possibly by anchoring the mitochondrial nucleoids to the inner mitochondrial membrane.
  • 基因功能参考文献：
    1. evidences have been obtained that ROS-dependent apoptosis is associated with an alteration of mitochondrial cAMP/PKA signal that causes degradation/proteolysis of Sirt3 that, in turn, promotes acetylation and proteolytic processing of OPA1 PMID: 27890624
    2. Retinal ischemia-reperfusion (I/R) or hypoxia-reoxygenation (H/R) injury induces Opa1 long isoforms loss. PMID: 26530815
    3. Data indicate that the expression of the dynamin-related GTPase OPA1 increased significantly in the pretreated groups, especially in the pre-exercised ischemia group compared with the non-treated groups. PMID: 24633199
    4. Chronic muscle use increases the ratio of opa1 leading to reticular mitochondria, whereas muscle disuse and aging result in a decrease in this ratio, culminating in fragmented mitochondria. PMID: 23494933
    5. data suggest that OPA1 cleavage is a likely convergence point for mitochondrial dysfunction and imbalances in mitochondrial fission and fusion induced by oxidative or nitrosative stress. PMID: 23220553
    6. OPA1 plays a role in synaptic maturation and dendritic growth through mitochondrial dynamics in neuronal functioning. PMID: 23543485
    7. These findings suggest that mitochondrial preservation after inhibition of NOS-2 may be useful for protecting retinal ganglion cells against glaucomatous damage. PMID: 21220562
    8. The data suggest an important and specific function of the OPA1 protein, not only in the optic nerve forming ganglion cells but also in the intrinsic signal processing of the inner retina. PMID: 15505078
    9. OPA1 is predominantly expressed in retinal ganglion cells of the normal rat retina and axons of the optic nerve. These findings may explain the selective vulnerability of retinal ganglion cells to OPA1 loss of function. PMID: 15912498
    10. Mammalian mitochondrial function and morphology is regulated through processing of OPA1 in a DeltaPsi-dependent manner. PMID: 16778770
    11. expression analyses of OPA1 in the rat auditory and vestibular organ PMID: 17828551
    12. data are the first to demonstrate OPA1 cleavage during neuronal apoptosis and they implicate caspases as indirect regulators of OPA1 processing in degenerating neurons PMID: 19046944
    13. These results indicate that OPA1 release from mitochondria triggered by acute intraocular pressure elevation is inhibited by blockade of glutamate receptor activation. PMID: 19122832
    14. Apoptotic cell death via reduction of OPA1 and mitochondrial fusion may contribute to heart failure progression. PMID: 19493956
