CD72 (Cluster of Differentiation 72), also known in murine biology as Lyb-2, is a protein active in the immune systemof animals. This gene is mapped to 9p13.3. It consists of two identical halves, each of about 39-43 kD, and is a C-type lectin. Its primarily locus of expression is B-cells, where it appears to mediate aspects of B-cell - T-cell interaction.
