Note: The complete sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
If the exact amino acid sequence of this recombinant protein is critical to your application, please explicitly request the full and complete sequence of this protein before ordering.
蛋白標簽：

N-terminal 6xHis-tagged
產品提供形式：

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.If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
復溶：

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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
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：

Promotes absorption of the essential vitamin cobalamin (Cbl) in the ileum. After interaction with CUBN, the CBLIF-cobalamin complex is internalized via receptor-mediated endocytosis.

1. the present findings reveal that High-altitude polycythemia -induced gastric mucosal lesion inspires the protection responses by up-regulating APOA4 and APOC3, and down-regulating GIF. PMID: 26485402
2. Our genetic screening of 154 families of patients with inherited cobalamin malabsorption revealed population-specific mutations, mutational hotspots, and functionally distinct regions in the three causal genes: CUBN, AMN, and GIF. PMID: 22929189
3. Acute lymphoblastic leukemia and vitamin B12 deficiency secondary to a gastric intrinsic factor gene mutation PMID: 22556038
4. crystal structure of the complex between IF-Cbl and the cubilin IF-Cbl-binding-region (CUB(5-8)) determined at 3.3 A resolution PMID: 20237569
5. A polymorphism in the gastric intrinsic factor gene is associated with congenital intrinsic factor deficiency. PMID: 14695536
6. The parameters obtained for ligand and receptor binding in this study indicate that both full-length 50-kDA intrinsic factor and its 30-kDa and 20-kDa fragments may be involved in assimilation of cobalamin. PMID: 15736970
7. possible basis for the lack of interchangeability of human and rat IF receptors is presented PMID: 17954916
8. The Q5R mutation of the intrinsic factor gene predisposes to adult-onset pernicious anemia & other causes of low vitamin B12. In this mutation, intrinsic factor secretion is preserved but B12 absorption may be impaired. PMID: 18338170
9. a specific GIF mutation to be responsible for all Juvenile cobalamin deficiency cases of West-African origin so far was identified PMID: 19036097
