target relevance
Protein names B-cell receptor CD22 (B-lymphocyte cell adhesion molecule) (BL-CAM) (Sialic acid-binding Ig-like lectin 2) (Siglec-2) (T-cell surface antigen Leu-14) (CD antigen CD22)
Gene names CD22,CD22 SIGLEC2
Protein family Immunoglobulin superfamily, SIGLEC (sialic acid binding Ig-like lectin) family
Mass 95348Da
Function FUNCTION: Most highly expressed siglec (sialic acid-binding immunoglobulin-like lectin) on B-cells that plays a role in various aspects of B-cell biology including differentiation, antigen presentation, and trafficking to bone marrow (PubMed:34330755, PubMed:8627166). Binds to alpha 2,6-linked sialic acid residues of surface molecules such as CD22 itself, CD45 and IgM in a cis configuration. Can also bind to ligands on other cells as an adhesion molecule in a trans configuration (PubMed:20172905). Acts as an inhibitory coreceptor on the surface of B-cells and inhibits B-cell receptor induced signaling, characterized by inhibition of the calcium mobilization and cellular activation. Mechanistically, the immunoreceptor tyrosine-based inhibitory motif domain is phosphorylated by the Src kinase LYN, which in turn leads to the recruitment of the protein tyrosine phosphatase 1/PTPN6, leading to the negative regulation of BCR signaling (PubMed:8627166). If this negative signaling from is of sufficient strength, apoptosis of the B-cell can be induced (PubMed:20516366). {ECO:0000269\|PubMed:20172905, ECO:0000269\|PubMed:20516366, ECO:0000269\|PubMed:34330755, ECO:0000269\|PubMed:8627166}.
Subellular location SUBCELLULAR LOCATION: Cell membrane {ECO:0000269\|PubMed:20172905}; Single-pass type I membrane protein.
Tissues TISSUE SPECIFICITY: B-lymphocytes.
Structure SUBUNIT: Predominantly monomer of isoform CD22-beta. Also found as heterodimer of isoform CD22-beta and a shorter isoform. Interacts with PTPN6/SHP-1, LYN, SYK, PIK3R1/PIK3R2 and PLCG1 upon phosphorylation. Interacts with GRB2, INPP5D and SHC1 upon phosphorylation (By similarity). May form a complex with INPP5D/SHIP, GRB2 and SHC1. {ECO:0000250\|UniProtKB:P35329, ECO:0000269\|PubMed:7618087, ECO:0000269\|PubMed:8627166, ECO:0000269\|PubMed:8647200}.
Post-translational modification PTM: Phosphorylation of Tyr-762, Tyr-807 and Tyr-822 are involved in binding to SYK, GRB2 and SYK, respectively. Phosphorylation of Tyr-842 is involved in binding to SYK, PLCG2 and PIK3R1/PIK3R2. {ECO:0000250\|UniProtKB:P35329}.; PTM: Phosphorylated on tyrosine residues by LYN. {ECO:0000250\|UniProtKB:P35329}.
Domain DOMAIN: Contains 4 copies of a cytoplasmic motif that is referred to as the immunoreceptor tyrosine-based inhibitor motif (ITIM). This motif is involved in modulation of cellular responses. The phosphorylated ITIM motif can bind the SH2 domain of several SH2-containing phosphatases.
