Background
Human Siglec-2, also known as B cell antigen CD22 or B lymphocyte cell adhesion molecule (BL-CAM), is a B cell restrictive glycoprotein that is expressed in the cytoplasm of progenitor B and pre-B cells and on the surface of mature B cells. CD22 mediates the interaction between B cells and may participate in the localization of B cells in lymphoid tissue. Siglec-2/CD22 binds to sialylated glycoproteins and plays a role in positive regulation by interacting with the Src family tyrosine kinases. It may also act as an inhibitory receptor by recruiting cytoplasmic phosphatase through its SH2 domain, blocking signal transduction through dephosphorylation of signaling molecules.
