CD72, also known as Lyb-2, is a type II membrane glycoprotein. CD72 is a pan-B cell marker expressed on pre-pre-B cells throughout B cell differentiation with the exception of plasma cells. It is also expressed on follicular dendritic cells, liver Kupffer cells, and splenic red pulp macrophages, but not on peripheral blood monocytes. CD100 and CD5 have been shown to be CD72 ligands. The CD100-CD72 interaction plays a role in maintenance of B cell homeostasis.
