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
The following tags are available.
N-terminal His-tagged
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.
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
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.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

May act as a scaffolding protein within caveolar membranes. Interacts directly with G-protein alpha subunits and can functionally regulate their activity. Acts as an accessory protein in conjunction with CAV1 in targeting to lipid rafts and driving caveolae formation. The Ser-36 phosphorylated form has a role in modulating mitosis in endothelial cells. Positive regulator of cellular mitogenesis of the MAPK signaling pathway. Required for the insulin-stimulated nuclear translocation and activation of MAPK1 and STAT3, and the subsequent regulation of cell cycle progression.
Gene References into Functions
  1. Cav-2beta isoform yielded by alternative translation initiation desensitizes insulin receptor (IR) via dephosphorylation by PTP1B, and subsequent endocytosis and lysosomal degradation of IR, causing insulin resistance. PMID: 29604334
  2. Results verified the presence of transcript III of cav-2 for the first time, but no protein associated was found. Also, a decreasing trend of cav-2 (transcripts I and II) were observed in tumoral tissues especially in stages I and II and seem to be associated with the incidence and promotion of breast cancer, especially in the initial stages of breast cancer. PMID: 28857238
  3. High CAV2 expression is associated with lung cancer. PMID: 26930711
  4. A-type lamin-dependent Caveolin-2 homo-oligomerization in the inner nuclear membrane microdomain is a precondition for pY19-Caveolin-2-mediated insulin-response epigenetic activation at the nuclear periphery. PMID: 27552914
  5. Caveolin-2 expression is necessary for the control of E2-dependent cellular proliferation of MCF-7 cells. PMID: 26480297
  6. variant in CAV2 is associated with increased age-of-onset of P. aeruginosa airway infection in cystic fibrosis cohort. PMID: 26047157
  7. Results present initial characterization of key proteins Cav2 and CFL1 as cellular factors that colocalize with M in viral inclusions and filaments and ZNF502 protein which appears to interact with RSV M in the nucleus. PMID: 25556234
  8. Our findings did not correspond with previous positive results, suggesting that CAV1-CAV2 variants studied in the present study are not important risk factors for Normal Tension Glaucoma. PMID: 23743525
  9. This study does not support an association between CAV2 variation and kidney transplant survival. PMID: 23667606
  10. The combination of the expression of the genes for PPARgamma, STMN1 and CAV2 was significantly predictive for early recurrence of non-muscle-invasive bladder cancer PMID: 21489836
  11. In contrast to wild-type-Cav-2, retroviral re-expression of Y19/27F-Cav-2 in Cav-2 knockout endothelial cells did not affect anti-proliferative effect of TGF-beta compared to empty vector. PMID: 22819829
  12. Stromal caveolin-2 expression were more frequent in anaplastic carcinoma and diffuse sclerosing variant of papillary carcinoma compared to conventional papillary thyroid carcinoma. PMID: 22236542
  13. CAV1 mRNA and protein levels are reduced by both NFBD1 knockdown and knockout independently of IR and p53 PMID: 21551225
  14. cav-2 acts as a modulator of cancer progression. PMID: 21373752
  15. We found preliminary evidence that CAV2 rs2270188 interacts with dietary fat to affect risk of type 2 diabetes. PMID: 21178094
  16. Single Nucleotide Polymorphisms in CAV2 is associated with primary open-angle glaucoma. PMID: 20835238
  17. In Caco-2 cells, a polarized cell line derived from human colon cancer that does not express caveolin 1 (Cav-1), there was no detectable expression of caveolin 2 (Cav-2). PMID: 12414992
  18. caveolin-2 may play a role in lamellar granule assembly, trafficking, and/or function. PMID: 12648214
  19. PPARgamma ligands increased the levels of caveolin-2 2-5-fold in a concentration-dependent manner within 24 h. Nonthiazolidinedione PPARgamma ligands elevated caveolin-2 protein 3-4-fold. PMID: 12813462
  20. New evidence demonstrating that Cav-2 undergoes phosphorylation at both tyrosines 19 and 27 also reveals that tyrosine phosphorylation of Cav-2 has no effect on its targeting to lipid rafts, but clearly disrupts hetero-oligomerization of Cav-2 with Cav-1. PMID: 15504032
  21. Heterologously and endogenously expressed D1 dopamine receptors in renal cells are associated with and regulated by caveolin-2. PMID: 15569306
  22. Overexpression of caveolin-2 is associated with inflammatory breast cancer PMID: 16244790
