This antibody is a single chain cell surface glycoprotein of 40 kDa, expressed by T cells, NK cells and thymocytes. CD7 is also expressed by tumour cells in some cases of acute myeloid leukaemia.

CD7 is a 40 kDa transmembrane, single-chain glycoprotein, which is a member of the immunoglobulin superfamily. CD7 is expressed by the majority of thymocytes and mature T cells, NK cells and pre-B cells. It plays an essential role in T-cell interactions and also in T-cell/B-cell interaction during early lymphoid development. The function of CD7 is not yet known although cross-linking of CD7 with antibodies induces a T cell transmembrane calcium flux and CD7 expression is induced by ionomycin. The CD7 Molecule has been reported to be the receptor for the IgM-Fc portion (FcR mu) on the surface of T cells.Synonyms: GP40, Leu-9, T-cell leukemia antigen, TP41
