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-SUMO-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.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
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：

Basically, we can dispatch the products out in 1-3 working days after receiving your orders. 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.
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：

May function as an inhibitor of the B-cell receptor signaling. May function in the B-cell-mediated immune response.
基因功能參考文獻：
1. We conclude that these activated B cells are a component of the local autoimmune response, and through their RANKL expression, can contribute to joint destruction. Furthermore, their expression of FcRL4 and their enrichment in the IgA isotype points towards a potential role for these cells in the link between mucosal and joint inflammation. PMID: 28343748
2. intraepithelial FcRL4(+) B-cells are present in the salivary glands of pSS patients. These cells are likely involved in the epithelial changes seen in pSS. Their enrichment in parotid glands may explain why MALT lymphomas in pSS patients preferentially develop at this specific location. PMID: 28390747
3. Commercially available IRTA1 antibody can immunohistochemically distinguish MALT lymphoma from other low-grade B-cell lymphomas. PMID: 27666766
4. Significantly increased FCRL4 mRNA only in Graves disease patients but not in Hashimoto patients compared to normal controls. PMID: 25738996
5. The observed significant gene-environment interaction suggests that drinking and cooking oil use with FCRL4 gene polymorphism has a significant interaction. PMID: 25012527
6. we provide evidence for involvement of HCK and FGR in FCRL4-mediated immunoregulation and for the functional importance of posttranslational modifications of the FCRL4 molecule. PMID: 25972488
7. IRTA1 and T-bet are positive markers for the diagnosis of nodal marginal zone lymphoma PMID: 23855758
8. Data indicate that signaling by HIV-1 gp120 through integrin alpha4beta7 resulted in increased expression of the immunosuppressive cytokine TGF-beta1 and FcRL4. PMID: 24162774
9. The cytological features, growth pattern and IRTA1 positivity in nodal marginal zone lymphomas suggest they may derive from IRTA1(+) perifollicular B cells or monocytoid B cells detectable in reactive lymph nodes. PMID: 22716304
10. The FCRL4 polymorphisms may play an important role in the susceptibility and severity of ankylosing spondylitis in the Chinese Han population. PMID: 22777505
11. In cellular binding assays, as a bona fide receptor FcRL4 binds efficiently to immunoglobulin (Ig)A. PMID: 22491254
12. Data suggest that expression of FcRL4 in B-cells results in inhibition of BCR signaling at point of Syk phosphorylation by mechanism that involves phosphorylation of FcRL4 and its association with SHP-1/SHP-2. PMID: 21908428
13. role of IRTA1 in the immune function of B cells within epithelia PMID: 12881317
14. Monocytoid B cells differ in their antigen profile (presence of IRTA1) from splenic and nodal marginal zone B cells. PMID: 16079106
15. Cell surface expression of this immunoregulatory molecule is restricted to a subpopulation of memory B cells. PMID: 16157685
16. Down-regulation of FCRL4 is associated with acute lymphoblastic leukemia. PMID: 18802695
17. FCRL4 is located on atypical memory B cells population significantly expanded in Plasmodium falciparum-exposed Malian adults and children PMID: 19592645
