Target Information
CD22 (BL-CAM) is a type 1 integral membrane glycoprotein with a molecular weight of 130–140 kDa. It is expressed in both the cytoplasm and membrane of B-lymphocytes and appears early in B-cell differentiation, similar to CD19.
CD22 membrane expression is limited to mature B cells (CD22+) and plasma cells (CD22−), making it useful for phenotyping mature leukemias. It is strongly expressed in hairy cell leukemia and positive in diffuse large B-cell lymphoma and nodular lymphocyte predominance Hodgkin’s lymphoma, but negative in classical Hodgkin’s lymphoma.
CD22 preferentially binds to α2,6-linked sialic acid and participates in B-cell receptor signaling regulation through tyrosine phosphorylation and interaction with Src family kinases. It can also act as an inhibitory receptor by recruiting cytoplasmic phosphatases that dephosphorylate signaling molecules.
