Description CD9 is a 24 kDa member of the transmembrane 4 superfamily (TM4-SF) of cell surface receptors. It is expressed strongly on platelets, lymphoid progenitor cells, activated lymphocytes and endothelia, and, weakly, on eosinophils, granulocytes, monocytes, and macrophages. CD9 functions as an adhesion molecule where it mediates platelet aggregation and activation.
