    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.

  • 蛋白標(biāo)簽:
    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.
  • 產(chǎn)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.
  • 復(fù)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.
  • 儲(chǔ)存條件:
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保質(zhì)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.
  • 貨期:
    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.
  • 注意事項(xiàng):
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點(diǎn)詳情

  • 功能:
    Functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA. This complex binds to a 40S ribosomal subunit, followed by mRNA binding to form a 43S pre-initiation complex. Junction of the 60S ribosomal subunit to form the 80S initiation complex is preceded by hydrolysis of the GTP bound to eIF-2 and release of an eIF-2-GDP binary complex. In order for eIF-2 to recycle and catalyze another round of initiation, the GDP bound to eIF-2 must exchange with GTP by way of a reaction catalyzed by eIF-2B. EIF2S1/eIF-2-alpha is a key component of the integrated stress response (ISR), required for adaptation to various stress: phosphorylation by metabolic-stress sensing protein kinases (EIF2AK1/HRI, EIF2AK2/PKR, EIF2AK3/PERK and EIF2AK4/GCN2) in response to stress converts EIF2S1/eIF-2-alpha in a global protein synthesis inhibitor, leading to a attenuation of cap-dependent translation, while concomitantly initiating the preferential translation of ISR-specific mRNAs, such as the transcriptional activators ATF4 and QRICH1, and hence allowing ATF4- and QRICH1-mediated reprogramming.
  • 基因功能參考文獻(xiàn):
    1. TorsinA was post-transcriptionally upregulated upon acute ER stress, suggesting a role in this response. Increased basal phosphorylation of eIF2alpha in DYT1 transgenic rats was associated with abnormal response to acute ER stress. Unbiased RNA-Seq-based transcriptomic analysis of embryonic brain tissue in heterozygous and homozygous DYT1 knockin mice confirmed presence of eIF2alpha dysregulation in the DYT1 brain. PMID: 29289717
    2. results demonstrate the sensitivity of eukaryotic initiation factor 2alpha-subunit (eIF2alpha) to stimulant exposure. Amphetamine possesses the ability to stimulate eIF2alpha phosphorylation in striatal and medial prefrontal cortex neurons in vivo in a dopamine D1 and D2 receptor-dependent manner. PMID: 27338925
    3. These results suggest a critical role of the mTOR/eIF2alpha pathway in hypoxic vascular remodeling and pulmonary arterial vascular smooth muscle cell proliferation of pulmonary hypertension. PMID: 26120832
    4. Dephosphorylation of eIF2alpha in the basolateral amygdala mediates memory reconsolidation of drug-paired stimuli. PMID: 25057203
    5. Data suggest maternal overweight due to high-fat diet up-regulates mTOR complex 1 (mechanistic target of rapamycin) activity and down-regulates eIF2 alpha subunit phosphorylation in placenta; such alterations contribute to placental/fetal overgrowth. PMID: 24006279
    6. eIF2a is hyperphosphorylated in the cortex of aged rats. PMID: 22883908
