Background

CD19 is a transmembrane glycoprotein specifically expressed in B cells and follicular dendritic cells. Its biological functions primarily rely on three tyrosine residues Y391, Y482, and Y513 in the cytoplasmic structural domain.

CD19 plays a role in many key B cell functions and, upon binding with its ligands CD21, CD81, or CD225, can recruit, activate, or amplify Src family protein tyrosine kinases, PI3K, and downstream Akt kinase, thereby intervening in the processes of B cell activation, proliferation, development, differentiation, and signal transduction.
