Target Details for CD22

Target: CD22 (CD22 Molecule (CD22))

Alternative Name: CD22 (CD22 Products)

Background:

Synonyms: 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,CD22,CD22,SIGLEC2,

Tissue Specificity: B-lymphocytes.

Background: CD22 is a surface glycoprotein of B lymphocytes that is rapidly phosphorylated on cytoplasmic tyrosines after antigen receptor cross-linking. It is a negative regulator of antigen receptor signaling whose onset of expression at the mature B cell stage may serve to raise the antigen concentration threshold required for B cell triggering. The human CD22 gene is expressed specifically in B lymphocytes and likely has an important function in cell-cell interactions. The B cell coreceptor CD22 plays an important role in regulating signal transduction via the B cell Ag receptor. And CD22 is located within the band region q13.1 of chromosome 19.
