  • 功能：
    Sialic-acid-binding immunoglobulin-like lectin (Siglec) that plays a role in mediating cell-cell interactions and in maintaining immune cells in a resting state. Preferentially recognizes and binds alpha-2,3- and more avidly alpha-2,6-linked sialic acid-bearing glycans. Upon engagement of ligands such as C1q or syalylated glycoproteins, two immunoreceptor tyrosine-based inhibitory motifs (ITIMs) located in CD33 cytoplasmic tail are phosphorylated by Src-like kinases such as LCK. These phosphorylations provide docking sites for the recruitment and activation of protein-tyrosine phosphatases PTPN6/SHP-1 and PTPN11/SHP-2. In turn, these phosphatases regulate downstream pathways through dephosphorylation of signaling molecules. One of the repressive effect of CD33 on monocyte activation requires phosphoinositide 3-kinase/PI3K.

Data suggest that two SNPs in CD33 (rs3865444A, rs12459419T) that are protective of Alzheimer disease result in splice variants (CD33M, CD33m); CD33M localizes predominantly at cell surface in macrophage cell line; CD33m is primary intracellular form in neutrophils and a microglia cell line; intracellular CD33m accumulates in peroxisomes; activation of macrophages/neutrophils does not mobilize CD33m to cell surface.
