CD72, a human homolog of murine Lyb-2, is a 45kD B-cell transmembrane glycoprotein. It is expressed in all stages of B-cell development except plasma cells and functions as a vital B-cell co-receptor. It exhibits a dual role during B-cell activation and development. It mediates positive signaling through activation of Grb2-Sos-Ras pathway resulting in activation of several downstream pathways including ERK and JNK pathways. ITIM motif present in the cytoplasmic domain of CD72 recruits SHP-1 upon tyrosine phosphorylation, resulting in negative regulation of BCR signaling. CD72 functions as a novel receptor for CD100/Sema4D, resulting in dephosphorylation of CD72 and regulation of negative signaling by CD72.
