    Liquid or 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.
  • 緩沖液：
    If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
    Note: If you have any special requirement for the glycerol content, please remark when you place the order.
    If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
  • 儲存條件：
    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：
    3-7 business days
  • 注意事項：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點詳情

  • 功能：
    Involved in transport from the endoplasmic reticulum to the Golgi apparatus. Required to maintain SEC16A localization at discrete locations on the ER membrane perhaps by preventing its dissociation. SAR1A-GTP-dependent assembly of SEC16A on the ER membrane forms an organized scaffold defining endoplasmic reticulum exit sites (ERES).
  • 基因功能參考文獻：
    1. Study data suggest that SAR1A and SAR1B are the critical regulators of trafficking of Nav1.5. Moreover, SAR1A and SAR1B interact with MOG1, and are required for MOG1-mediated cell surface expression and function of Nav1.5. PMID: 30251687
    2. Study shows that the bona fide nonglycoprotein Nox5, a transmembrane superoxide-producing NADPH oxidase, is transported to the cell surface in a manner resistant to co-expression of Sar1 (H79G), a GTP-fixed mutant of the small GTPase Sar1, which blocks COPII vesicle fission from the endoplasmic reticulum. PMID: 29718541
    3. No associations were observed between any of the secretion associated Ras related GTPase 1A (SAR1a) promoter variants and baseline fetal hemoglobin HbF among sickle cell disease (SCD) patients. PMID: 28499394
    4. Sar1 is a novel regulator of endoplasmic reticulum-mitochondrial contact sites in the metazoans. PMID: 27101143
    5. SAR1A gene silencing in hepatocytes mimics the effect of ethanol: dedimerization of giantin, arresting PDIA3 in the endoplasmic reticulum (ER) and large-scale alterations in Golgi architecture. PMID: 26607390
    6. Data indicate that hydroxyurea (HU) induces SAR1 protein expression, which in turn activates gamma-globin expression, predominantly through the Gialpha/JNK/Jun pathway. PMID: 24914133
    7. although Sar1A antagonizes the lipoprotein secretion-promoting activity of Sar1B, both isoforms modulate the expression of genes encoding cholesterol biosynthetic enzymes and the synthesis of cholesterol de novo. PMID: 24338480
    8. Sar1 mutant proteins added to metaphase-arrested Xenopus laevis egg extracts cause dramatic effects on membrane organization. PMID: 22605651
    9. the behavior of the human of Sar1A and Sar1B, a key component of the COPII family of vesicle coat proteins, was examined. PMID: 22974979
    10. Sedlin bound and promoted efficient cycling of Sar1, a guanosine triphosphatase that can constrict membranes, and thus allowed nascent carriers to grow and incorporate procollagen prefibrils. PMID: 23019651
    11. lipid-directed and tether-assisted Sar1 organization controls membrane constriction to regulate ER export. PMID: 20624903
    12. the intracellular trafficking of hCaR from the endoplasmic reticulum is Sar1-dependent via coat protein complex-II vesicles. PMID: 20457124
    13. The Sec31 fragment stimulates GAP activity of Sec23/24, and a convergence of Sec31 and Sec23 residues at the Sar1 GTPase active site explains how GTP hydrolysis is triggered leading to COPII coat disassembly. PMID: 17981133
    14. Sar 1 H79G mutants efficiently blocked the plasma membrane trafficking of the Kir3.1/Kir3.4 complex however they did not block the Gbeta1gamma2/Kir3.1 interaction. PMID: 19135528
    15. Kir6.2 contains a di-acidic endoplasmic reticulum exit signal, which promotes endoplasmic reticulum exit via a process that requires Sar1. PMID: 19357197
