    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 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.
  • 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.
  • 保质期：
    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.

  • 功能：
    Mitochondrial proton/calcium antiporter that mediates proton-dependent calcium efflux from mitochondrion. Crucial for the maintenance of mitochondrial tubular networks and for the assembly of the supercomplexes of the respiratory chain. Required for the maintenance of the tubular shape and cristae organization. In contrast to SLC8B1/NCLX, does not constitute the major factor for mitochondrial calcium extrusion.

    1. these results revealed that the knockdown of LETM1 exhibited tumor suppressive effects, possibly by controlling the downstream Wnt/beta-catenin signaling pathway. PMID: 29048663
    2. Data indicate a positive association between LETM1 up-regulation, YAP1 nuclear localization and high PDGFB expression. PMID: 27556512
    3. LETM1 plays an important role in the progression of breast cancer PMID: 26722481
    4. LETM1 protein overexpression is associated with Triple negative breast cancer progression, and may be a potential biomarker for poor prognostic evaluation of Triple negative breast cancer. PMID: 25617527
    5. LETM1 plays an important role in the progression of head and neck squamous cell carcinoma. PMID: 24689060
    6. Letm1 expression is decreased in patients with intractable TLE and a rat model of epilepsy. Down-regulation of Letm1 leads to increases mitochondrial swelling and decreased MT-CYB expression, which is associated with susceptibility to seizures. PMID: 23645710
    7. Reconstitution of LETM1 or antioxidant overexpression rescued mitochondrial Ca(2+) transport and bioenergetics PMID: 25077561
    8. These findings identify novel cellular phenotypes in Wolf-Hirschhorn syndrome attributable to a 50% reduction in LETM1 expression level. PMID: 24626991
    9. Haploinsufficiency of WHSC1 and/or LETM1 contributes to Wolf-Hirschhorn Syndrome, but that loss of distinct and/or additional genes in 4p16.3 is necessary for the expression of the core Wolf-Hirschhorn Syndrome phenotype. PMID: 23963300
    10. NCLX, but not LETM1, mediates Ca(2+) extrusion from mitochondria. By controlling the duration of matrix Ca(2+) elevations, NCLX contributes to the regulation of NAD(P)H production and to the conversion of Ca(2+) signals into redox changes. PMID: 24898248
    11. Functional properties of Letm1 described in study are remarkably similar to those of the H(+)-dependent Ca(2+) transport mechanism identified in intact mitochondria. PMID: 24344246
    12. Data indicate that loss of Letm1 contributes to the pathology of Wolf-Hirschhorn syndrome and may contribute to seizure phenotypes by reducing glucose oxidation and other specific metabolic alterations. PMID: 23716663
    13. Summarizes the current state of the art about the functions of LETM1 and its role in pathophysiology, with some emphasis on whether it is a feasible candidate for regulation of mitochondrial Ca2+ homeostasis. PMID: 22641639
    14. Letm1 and UCP2/3 independently contribute to two distinct, mitochondrial Ca(2+) uptake pathways in intact endothelial cells. PMID: 21613221
    15. we have identified a novel submicroscopic duplication involving dosage sensitive genes TACC3, FGFR3, and LETM1. PMID: 21815251
    16. LETM1 suppressed lung cancer cell growth in vitro and in vivo. PMID: 20824095
    17. LETM1 is evolutionarily conserved throughout the eukaryotic kingdom and located in the mitochondria. PMID: 14706454
    18. Here, we present cellular and biochemical analysis of Letm1 PMID: 17606466
    19. Study shows that human LETM1 is located in the inner membrane, exposed to the matrix and oligomerized in higher molecular weight complexes of unknown composition; down-regulation of LETM1 caused 'necrosis-like' death, without activation of caspases. PMID: 17925330
    20. the LETM1-mediated regulation of the mitochondrial volume and its interaction with the mitochondrial AAA-ATPase BCS1L that is responsible for three different human disorders PMID: 18628306
    21. LETM1 protein is a novel binding partner for Carboxyl-terminal modulator protein that may play an important role in mitochondrial fragmentation via optic atrophy type 1-cleavage. PMID: 19168126
    22. Data suggest that LETM1 serves as an anchor protein for complex formation with the mitochondrial ribosome and regulates mitochondrial biogenesis. Increased expression of LETM1 in human cancer suggests that dysregulation of LETM1 features in tumorigenesis. PMID: 19318571
    23. Letm1, was found to specifically mediate coupled Ca2+/H+ exchange; RNAi knockdown, overexpression, and liposome reconstitution of the purified Letm1 protein demonstrate that Letm1 is a mitochondrial Ca2+/H+ antiporter PMID: 19797662
