Background
CD72 is a coreceptor of B cell receptor (BCR), which is expressed on all B cells starting at the pre-B cell stage, but its expression decreases significantly during differentiation into plasma cells. CD72 is a transmembrane receptor that is expressed as a homodimer. It has a conserved intracellular domain, which contains an immunoreceptor tyrosine-based inhibitory motif (ITIM) that binds SHP-1, a tyrosine phosphatase, and an ITIM-like motif that binds Grb2, an adaptor protein required to activate the Ras pathway. CD72 is known to play an important role in various B cell processes, including proliferation, apoptosis and differentiation. Mouse CD72 negatively regulates BCR signaling by recruiting Src homology 2 domain-containing protein tyrosine phosphatase-1 (SHP-1) at ITIM.
