CD19 functions as coreceptor for the B-cell antigen receptor complex (BCR) on B-lymphocytes. It decreases the threshold for activation of downstream signaling pathways and for triggering B-cell responses to antigens. CD19 also activates signaling pathways that lead to the activation of phosphatidylinositol 3-kinase and the mobilization of intracellular Ca2+ stores.
