  • 功能:
    Putative adhesion molecule that mediates sialic-acid dependent binding to cells. Preferentially binds to alpha-2,3- or 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.
  • 基因功能参考文献:
    1. The SIGLEC9 rs2075803 G/rs2258983 A haplotype, which corresponds to a Siglec-9 variant that is less effective at suppressing inflammatory response, may be a risk factor for the development of emphysema. PMID: 27878892
    2. Glycophorin A, the most abundant sialoglycoprotein on erythrocytes, engaged neutrophil Siglec-9, a sialic acid-recognizing receptor known to dampen innate immune cell activation. These studies demonstrate a previously unsuspected role for erythrocytes in suppressing neutrophils ex vivo and in vitro and help explain why neutrophils become easily activated after separation from whole blood. PMID: 28416510
    3. Data suggest that sialic acid-binding Ig-like lectin-9 (Siglec-9)may serve as a potential diagnostic and therapeutic target for rheumatoid arthritis (RA). PMID: 28273363
    4. The mechanism of the Siglec-9 and AOC3 interaction is mediated both by protein-sugar interactions via the V domain and by the protein-protein interactions via the C22 Siglec9 domain. PMID: 27893774
    5. This work defines a critical role for aberrantly glycosylated MUC1 and identifies an activating pathway that follows engagement of Siglec-9. PMID: 27595232

    12. Siglec-9 expressed on immune cells may play a role as a potential counterreceptor for MUC1 and that this signaling may be another MUC1-mediated pathway and function in parallel with a growth factor-dependent pathway. PMID: 24045940
    13. The Siglec-9 peptide binding to the enzymatic groove of VAP-1 can be used for imaging conditions, such as inflammation and cancer. PMID: 21821708
    14. Siglec-9 A391C was the only polymorphism related to TCR-mediated signaling in human Siglec-9, resulting in less inhibition compared to the wild type. PMID: 20733319
    15. These results suggest that Siglec-9 expressed on DCs is involved in immunoregulation through ligation with mucins in an epithelial cancer patient. PMID: 20971061
    16. MUC16-Siglec-9 binding likely mediates inhibition of anti-tumor immune responses. PMID: 20497550
    17. Septic shock patients exhibit different ex vivo death responses of blood neutrophils after Siglec-9 ligation early in shock. PMID: 19295491
    18. Binding studies on recombinant human Siglec-9 show recognition of both Neu5Ac and Neu5Gc; in striking contrast, chimpanzee and gorilla Siglec-9 strongly prefer binding Neu5Gc. PMID: 14693915
    19. Siglec-9 can inhibit Fc epsilon receptor I-mediated serotonin release from rat basophilic leukemia cells and recruit the tyrosine phosphatases SHP-1 and SHP-2. PMID: 15557178
    20. data suggest that apoptotic (ROS- and caspase-dependent) and nonapoptotic (ROS-dependent) death pathways are initiated in neutrophils via Siglec-9 PMID: 15827126
