Background

Function：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 (PubMed:10611343, PubMed:11320212, PubMed:15597323). Preferentially recognizes and binds alpha-2,3- and more avidly alpha-2,6-linked sialic acid-bearing glycans (PubMed:7718872). 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 (PubMed:10887109, PubMed:28325905). These phosphorylations provide docking sites for the recruitment and activation of protein-tyrosine phosphatases PTPN6/SHP-1 and PTPN11/SHP-2 (PubMed:10206955, PubMed:10556798, PubMed:10887109). In turn, these phosphatases regulate downstream pathways through dephosphorylation of signaling molecules (PubMed:10206955, PubMed:10887109). One of the repressive effect of CD33 on monocyte activation requires phosphoinositide 3-kinase/PI3K (PubMed:15597323)

Subcellular Localization：Cell membrane; Single-pass type I membrane protein; Peroxisome

Expression：
Tissue_specificity:Monocytic/myeloid lineage cells. In the brain, CD33 is mainly expressed on microglial cells

Isoforms & Post-Translational Modification：P20138 has 3 isomers: P20138-1: 39825 Da (predicted); P20138-2: 33890 Da (predicted); P20138-3: 25293 Da (predicted).
Glycosylated. Glycosylation at Asn-100 is critical for regulating ligand recognition;Phosphorylation of Tyr-340 is involved in binding to PTPN6 and PTPN11. Phosphorylation of Tyr-358 is involved in binding to PTPN6. LCK phosphorylates Tyr-340 efficiently and Tyr-358 to a lesser extent

Subunit：Homodimer; disulfide-linked (PubMed:10887109). Interacts with PTPN6/SHP-1 and PTPN11/SHP-2 upon phosphorylation (PubMed:10206955, PubMed:10556798).
