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.
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.
and FAQs
Protein 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

Catalyzes the stereospecific oxidation of squalene to (S)-2,3-epoxysqualene, and is considered to be a rate-limiting enzyme in steroid biosynthesis.
Gene References into Functions
  1. Taken together, our results support a model whereby the amphipathic helix in squalene monooxygenase N100 attaches reversibly to the ER membrane depending on cholesterol levels; with excess, the helix is ejected and unravels, exposing a hydrophobic patch, which then serves as a degradation signal. PMID: 28972164
  2. Both HMGCR and SQLE promoters have two SREs that may act as a homing region to attract a single SREBP-2 homodimer. PMID: 28342963
  3. Data indicate that microRNA miR-133b-dependent squalene epoxidase (SQLE) plays a critical role in the potential metastasis mechanisms in esophageal squamous cell carcinoma (ESCC). PMID: 28069586
  4. our results pinpoint SQLE as a bona fide metabolic oncogene by amplification, and as a therapeutic target in BC. These findings could have implications in other cancer types. PMID: 26777065
  5. this study have identified a Squalene Monooxygenase region integrally associated with the endoplasmic reticulum membrane that is likely to interact with cholesterol or respond to cholesterol-induced membrane effects. PMID: 26434806
  6. overexpression of SQLE in HCC cells promoted cell proliferation and migration, while downregulation of SQLE inhibited the tumorigenicity of Hepatocellular carcinoma cells in vitro and in vivo. PMID: 25787749
  7. Data suggest that unsaturated fatty acids (oleate; oleoyl-CoA) stabilize SM/SQLE (which catalyzes 1st oxygenation step in cholesterol synthesis) most likely via inhibition of poly-ubiquitination by MARCH6 (membrane-associated ring finger [C3HC4] 6). PMID: 24840124
  8. MARCH6 and squalene monooxygenase (SM) physically interact, and consistent with MARCH6 acting as an E3 ligase, its overexpression reduces SM abundance in a RING-dependent manner. PMID: 24449766
  9. functional promotor regions involved in transcription was determined PMID: 12083769
  10. A cDNA library consisting of 220 upregulated genes in tumour tissue was established and named as LSCC. Differential expression was confirmed in five of these genes, including IGFBP5, SQLE, RAP2B, CLDN1, and TBL1XR1. PMID: 17316888
  11. Distant metastasis-free survival in stage I/II breast cancer cases was significantly inversely related to SQLE mRNA in multivariate Cox analysis in two independent patient cohorts of 160 patients each PMID: 18728668
