CD19 is a 95kD transmembrane glycoprotein with two Ig-like C2-set domains. CD19 regulates B cell development and activation through interactions with CD21, CD22, and the B cell receptor. CD19 polymorphisms and upregulation lead to the development of autoimmunity by promoting autoantibody production. Within the extracellular domain, human CD19 shares 57% aa sequence identity with mouse and rat CD19.
