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
May act as a GTPase-activating protein for RAB2A, RAB8A, RAB10 and RAB14. Isoform 2 promotes insulin-induced glucose transporter SLC2A4/GLUT4 translocation at the plasma membrane, thus increasing glucose uptake.
Gene References into Functions
  1. C-terminal region (CTR) region is largely alpha-helical and mediates TBC1D4 RabGAP dimerization PMID: 28545963
  2. Disruption of TBC1D4 is common among North American Inuit, resulting in exclusively elevated postprandial glucose. This leads to underdiagnosis of type 2 diabetes, unless an OGTT is performed. PMID: 27561922
  3. AS160 regulates glucose-independent eukaryotic cell proliferation through p21-dependent control of the cell cycle. PMID: 27152871
  4. AS160 and TBC1D1 phosphorylations were evident 30 min after exercise. PMID: 24876356
  5. homozygous carriers of a nonsense p.Arg684Ter variant have markedly higher concentrations of plasma glucose and serum insulin 2 hours after an oral glucose load compared with individuals with other genotypes PMID: 25043022
  6. Findings suggest that a dampening of insulin-induced phosphorylation of AS160 on specific sites in skeletal muscle contributes to the insulin resistance evident in a sedentary aging population PMID: 23801578
  7. insulin resistance in muscles from healthy individuals is associated with suppression of site-specific phosphorylation of AS160 PMID: 22028408
  8. AS160 interacts with the large cytoplasmic NP domain of the alpha-subunit of the Na(+),K(+)-ATPase. AMP-stimulated protein kinase (AMPK) and AS160 participate in a common pathway to modulate the cell surface expression of the Na(+),K(+)-ATPase. PMID: 20943949
  9. Crystal structures of human TBC1D1 and TBC1D4 (AS160) RabGTPase-activating protein (RabGAP) domains reveal critical elements for GLUT4 translocation. PMID: 21454505
  10. AS160 phosphotyrosine-binding domain constructs inhibit insulin-stimulated GLUT4 vesicle fusion with the plasma membrane PMID: 21454690
  11. Impaired insulin-induced site-specific TBC1D4 phosphorylation may contribute to skeletal muscle insulin resistance in type 2 diabetes. PMID: 20938636
  12. results show AS160 phosphorylation level is frequently increased in breast cancer; results implicate a possible role of AS160 in breast tumorigenesis and suggest that p-AS160 might be useful as a marker and a potential novel treatment target PMID: 20574165
  13. WNK1 promotes cell surface expression of glucose transporter GLUT1 by regulating a Tre-2/USP6-BUB2-Cdc16 domain family member 4 (TBC1D4)-Rab8A complex PMID: 20937822
  14. S711 is a novel TBC1D4 phosphorylation site regulated by AMPK in skeletal muscle. PMID: 19923418
  15. KIAA0603 is likely to be a Rab GAP that participates in the regulation of activated T cells in atopic dermatitis PMID: 15304337
  16. In this study, we determined the expression of and in vivo insulin action on AS160 in skeletal muscle of normal and type 2 diabetic patients. PMID: 15919790
  17. results indicate that AS160 is a Rab GAP, and suggest novel Rabs that may participate in GLUT4 translocation PMID: 15971998
  18. AS160 is phosphorylated in a time-dependent manner during moderate-intensity exercise. PMID: 17077344
  19. Regulation of AS160 and interaction with 14-3-3 in skeletal muscle are influenced by resistance exercise and insulin but do not fully explain the effect of resistance exercise on whole-body insulin action. PMID: 17369524
  20. Effects of endurance exercise training on insulin signaling and AS160 in human skeletal muscle PMID: 17513702
  21. AS160 is a common target of insulin, IGF-1, EGF, PMA and AICAR, these stimuli induce distinctive patterns of phosphorylation and 14-3-3 binding, mediated by at least four protein kinases. PMID: 17617058
  22. Impaired insulin signaling through Akt and AS160 in part explains insulin resistance at the molecular level in skeletal muscle in polycystic ovary syndrome. PMID: 17977950
  23. AS160, previously recognized as a key player in insulin signaling in skeletal muscle and adipose tissue, is also a major effector of protein kinase B/Akt signaling in the beta-cell. PMID: 18276765
  24. The transcript variant 2 of AS160 in contrast to full-length AS160 is a novel regulator of glucose transport that positively influences glucose-uptake rates. PMID: 18771725
  25. muscle TBC1D4 phosphorylation across the leg is increased during recovery following resistance exercise PMID: 18845784
  26. Specific phosphorylation of TBC1D4 in human skeletal muscle in response to physiological exercise-induced hyperinsulinemia. PMID: 19252894
  27. Prematurely truncated TBC1D4 protein tended to increase basal cell membrane GLUT4 levels (P = 0.053) and significantly reduced insulin-stimulated GLUT4 cell membrane translocation (P < 0.05). PMID: 19470471
