Western blot analysis of extracts from L1210(lane 1(40μg) ),Raji(lane 2(40μg) ),Ramos(lane 3(40μg) ),Raw246.7(lane 4(40μg) ),HEK293(lane 5(40μg) ), Jurkat(lane 6(40μg) ),Hela(lane 7(40μg) )and Mouse spleen(lane 8(40μg) ) using CD22 antibody. Proteins were transferred to a NC membrane and blocked with 5% Skim milk in TBST for 2 hour at room temperature. The primary antibody ( 1/1000) and Loading control antibody (GAPDH，1/1000) was used in 5% Skim milk in TBST at 4°C overnight. Goat Anti-Mouse IgG-HRP Secondary Antibody (1/10,000) was used for 1 hour at room temperature.
Flow cytometric analysis of 1X10^6 Ramos cells labeling CD22 Antibody(red). Cells were fixed with 4% paraformaldehyde and permeabilised with 0.2% Triton X-100. Then stained with the primary antibody at 1/400 dilution overnight at 4℃. AF 488 Goat Anti-mouse IgG H&L was used as the secondary antibody at 1/1,000 dilution for 45 minutes at room temperature. Mouse IgG Isotype Control (blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
Immunofluorescence analysis of Hela cells labeling CD22 antibody at 1/50 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 15 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature.Cells were then incubated with CD22 antibody at 1/50 dilution in 1% BSA in PBST overnight at 4 ℃. AF 488 Goat Anti-mouse IgG H&L (green) was used as the secondary antibody at 1/500 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue)

Background

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)

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

Expression：
Tissue_specificity:B lymphocytes

Isoforms & Post-Translational Modification：P20273 has 5 isomers: P20273-1: 95348 Da (predicted); P20273-2: 75799 Da (predicted); P20273-3: 85675 Da (predicted); P20273-4: 84480 Da (predicted); P20273-5: 75354 Da (predicted).
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;Phosphorylated on tyrosine residues by LYN

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
