SIGLEC1 antibodies

靶点详情

  • 功能：
    Acts as an endocytic receptor mediating clathrin dependent endocytosis. Macrophage-restricted adhesion molecule that mediates sialic-acid dependent binding to lymphocytes, including granulocytes, monocytes, natural killer cells, B-cells and CD8 T-cells. Preferentially binds to alpha-2,3-linked sialic acid. Binds to SPN/CD43 on T-cells. May play a role in hemopoiesis.

    3. Our findings evidenced for the first time the novel association between SIGLEC1 rs3859664 SNP and active pulmonary TB.

    5. The results reveal marked differences between afferent and efferent ymphatic endothelial cells and identify molecules on lymphatic vessels.
