General description

CD22 (cluster of differentiation 22) is a 140 kDa single-spanning membrane glycoprotein present on the surface of B cells. This gene belongs to the sialic acid-binding Ig-type lectin (Siglec) family. CD22 is mapped to human chromosome 19q13.

Immunogen

The antiserum was produced against synthesized peptide derived from human BL-CAM around the phosphorylation site of Tyr807.

Immunogen Range: 776-825

Biochem/physiol Actions

CD22 (cluster of differentiation 22) helps to maintain B-cell homeostasis. This molecule act as an inhibitory coreceptor of the BCR (B cell receptor). CD22 is considered as a response regulator to control several aspects of B cell functions. Deficiency in CD22 or its pathways may contribute to autoimmunity.
