Alternative Name CD19 (CD19 Antibody Abstract)
Background CD19 is a member of the immunoglobulin superfamily with 556 amino acid and two immunoglobulin-like C2-type domains. As a cell surface protein, CD19 is known to form a complex with CD21, CD81 and CD225 in the membrane of mature B cells. A major function of CD19 is to assemble with the antigen receptor of B lymphocytes so as to decrease the threshold for antigen receptor dependent stimulation thus enhancing the specificity and sensitivity of B cells towards antigens. CD19 is an important protein for B cell antigen receptor signaling and regulation and also acts as a specialized adaptor protein for the amplification of Src family needed for this purpose. Regulation of growth of B cells is a major function of CD19 and its expression is confined to only B lymphocytes and follicular dendritic cells of the hematopoietic system. Increased expression of CD19 induces the production of auto-antibody thus giving an insight to the regulatory role of CD19 in autoimmunity. Defects in CD19 are a cause of hypogammaglobulinemia.
