Background

CD2 (also known as LFA-2, T-cell surface antigen T11/Leu-5, LFA-3 receptor, E-rosette receptor) is a member of the immunoglobulin superfamily. It is a transmembrane glycoprotein present on T cells, NK cells, thymocytes and dendritic cells. CD2 functions as an adhesion molecule, binding with lymphocyte function-associated antigen (LFA-3/CD58) in humans. It has also been reported to interact with CD48 and CD59. CD2 plays important roles in cell adhesion between T-cells/NK cells and other cell types, T-cell activation, NK-cell activation, and thymocyte development.
