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 10xHis-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：

Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0
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：

Putative adhesion molecule that mediates sialic-acid dependent binding to cells. Binds equally to alpha-2,3-linked and alpha-2,6-linked sialic acid. The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface.
基因功能參考文獻：
1. PSGL1 and Siglec-5 are in close proximity at the leukocyte surface.SPSGL1 is a ligand for Siglec-5 and interacts with Siglec-5 ectodomain.Siglec-5 plays a role in PSGL1-mediated leukocyte rolling and the inflammatory response in general. PMID: 27892504
2. An unbiased screen revealed Hsp70 as a ligand for Siglec-5 and Siglec-14. Hsp70 stimulation through Siglec-5 delivers an anti-inflammatory signal, while stimulation through Siglec-14 is pro-inflammatory. PMID: 26459514
3. Data indicate that the Siglec-5/14 genotype influences neutrophil responses to group B Streptococcus. PMID: 24799499
4. we found that secretory IgA is taken up by M cells via the Dectin-1 receptor, with the possible involvement of Siglec-5 acting as a co-receptor. PMID: 24068891
5. These studies demonstrate the Siglec5 carbohydrate recognition domain alone is sufficient for binding sialylated carbohydrates and provide a foundation for further investigation of Siglec5 structure and function. PMID: 23321067
6. Siglec-5 expression protects T cells from HIV-1- and apoptosis-induced cell death and contributes to the different outcomes of HIV-1 infection in humans and chimpanzees. PMID: 22945238
7. Human Siglec-5 inhibitory receptor and immunoglobulin A (IgA) have separate binding sites in streptococcal beta protein. PMID: 21795693
8. Siglec-5 expression correlates with lack of proliferation in a subset of human cells, and is upregulated by activation of chimpanzee but not human lymphocytes. PMID: 20231688
9. expression of Siglec-5 on cells of the myelomonocytic lineage and alteration of its expression by inflammatory stimuli suggest a role for this protein in cell/cell interactions following microbial exposure. PMID: 12763136
10. Siglec-5 can be classified as an inhibitory receptor with the potential to mediate SHP-1 and/or SHP-2-dependent signaling in the absence of tyrosine phosphorylation. PMID: 15769739
11. Siglecs-5 did not interact with sulfate derivatives of LacNAc and sulfated oligosaccharides containing sialic acid. PMID: 16732727
12. The expression levels of Siglec-5 were high or detectable in bone marrow plasma from AML patients and serum from normal donors. PMID: 16828866
13. Siglec-14 and Siglec-5 appear to be the first glycan binding paired receptors. Near-complete sequence identity of the amino-terminal part of human Siglec-14 and Siglec-5 indicates partial gene conversion between SIGLEC14 and SIGLEC5. PMID: 17012248
14. Siglec-5 is identified as a receptor for alpha-1-acid glycoprotein (AGP) 1 in human neutrophils. PMID: 17675532
15. Structural implications of SIGLEC5-mediated sialoglycan recognition are reported. PMID: 18022638
16. Group B Streptococcus beta protein binding to Siglec-5 functions to impair leukocyte phagocytosis, oxidative burst, and extracellular trap production, promoting bacterial survival. PMID: 19596804
