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.
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

Integrin alpha-V:beta-6 (ITGAV:ITGB6) is a receptor for fibronectin and cytotactin. It recognizes the sequence R-G-D in its ligands. Internalization of integrin alpha-V/beta-6 via clathrin-mediated endocytosis promotes carcinoma cell invasion. ITGAV:ITGB6 acts as a receptor for fibrillin-1 (FBN1) and mediates R-G-D-dependent cell adhesion to FBN1. Integrin alpha-V:beta-6 (ITGAV:ITGB6) mediates R-G-D-dependent release of transforming growth factor beta-1 (TGF-beta-1) from regulatory Latency-associated peptide (LAP), thereby playing a key role in TGF-beta-1 activation.; (Microbial infection) Integrin ITGAV:ITGB6 acts as a receptor for Coxsackievirus A9 and Coxsackievirus B1.; (Microbial infection) Integrin ITGAV:ITGB6 acts as a receptor for Herpes simplex virus-1/HHV-1.
Gene References into Functions
  1. these findings demonstrate that JunB and CBP-mediated histone hyperacetylation are responsible for TGF-beta1 induced ITGB6 transcription in oral squamous cell carcinoma (OSCC) cells, suggesting that epigenetic mechanisms are responsible for the active transcription expression of ITGB6 induced by TGF-beta1 in OSCC cells. PMID: 29274289
  2. Taken together, our results indicate that integrin beta6 promotes tumor invasiveness in a Rac1-dependent manner and is a potential biomarker for tumor metastasis. PMID: 27440504
  3. The increased regional and distant metastasis observed in HER2+ tumors with high levels of ITGB6 might be mediated by the canonical Rho-Rac pathway through increased expression of MMP9 and MMP15. PMID: 27184932
  4. Rare missense variant c.898G>A (p.(Glu300Lys)) in ITGB6 causes not only dentogingival anomalies but also intellectual disability and alopecia. PMID: 26695873
  5. Treatment of these cells with the dual-specificity tyrosine-kinase inhibitor lapatinib led to downregulation of epithelial-to-mesenchymal transition as indicated by lower levels of SNAI1 and SNAI2 transcripts, integrin AVB6, and matrix metalloproteinase 9 protein PMID: 28349782
  6. Integrin b6 markedly promoted the proliferation and invasion of pancreatic carcinoma cells and induced ETS1 phosphorylation in an ERK-dependent manner, leading to the upregulation of matrix metalloprotease-9, which is essential for b6-mediated invasiveness of pancreatic carcinoma cells PMID: 26547582
  7. AG/GG genotypes of ITGB6 rs4665162 gene were associated with a higher risk of radiation pneumonitis (RP) in patients with lung cancer receiving radiotherapy and thus may serve as a reliable predictor of RP. PMID: 26449830
  8. A novel homozygous ITGB6 mutation causing isolated amelogenesis imperfecta, and this advances the understanding of normal and pathologic enamel development. PMID: 25431241
  9. These data reveal a novel role for Elk1 regulating ITGB6 expression and highlight how dysregulation of Elk1 can contribute to human disease. PMID: 26861876
  10. Integrin beta6 expression correlated significantly with MMP-9 expression, and may be a valuable recurrence indicator for follicular thyroid carcinomas PMID: 24844802
  11. The results indicated that MMP-9-degraded Fibronectin can adjust constituents of the avb6 heterodimers at the early phase and significantly elevate amounts of b6 integrin subunits at a later period PMID: 26134759
  12. Results shows that ITGB6 promoter contains a functional TATA box and that STAT3 and C/EBPalpha are involved in its positive regulation in oral squamous cell carcinoma cells. PMID: 25816241
  13. targeting eIF4E in integrin ava6 expressing tumors can be a potential therapeutic strategy for patients with colon cancer. PMID: 25982998
  14. In conclusion NSCLC cell lines, positive for E-Cadherin,EpCAM and avb6 expression, activate normal fibroblasts through avbeta6/TGFbeta signalling in vitro, and influence both gene expression and response to therapeutic agents. PMID: 24488011
