Background
T cell
surface antigen CD2 is a type I glycoprotein belonging to the Ig superfamily and
is expressed on T cells, NK cells, B cells and some antigen presenting cells.
CD2 functions as an activator of T lymphocytes and thymocytes (1). Mature human CD2 consists of a 185 amino
acid (aa) extracellular domain (ECD), a 26 aa transmembrane segment, and a
116 aa cytoplasmic tail. The
extracellular domain is composed of two immunoglobulin-superfamily domains with
highly-charged binding regions (2). Within the ECD, human CD2 shares 47% and
48% aa sequence identity with mouse and rat CD2, respectively. It interacts with both CD58 and CD59
directly to activate T cells and their adhesion pathways (3). The
conformational flexibility of the CD2 molecule affects function through the
conformational status of the adhesive ligands (4). Together with PSTPIP1, CD2
works to regulate T cell activation (5). These two proteins colocalize with a
second CD2-binding protein to signal immunological synapse formation in T cells
(6). CD2 is an adhesion molecule present on the cell surface of T cells, natural
killer (NK) cells, and B cells; and its interaction with CD58 on
antigen-presenting cells plays an important role in their immune reaction (7).
CD2-CD58 interactions play a critical role in the anti-tumor immune response,
and restoration of this signaling is an important strategy for anti-tumor
therapy (8). Furthermore, CD2-CD58 interactions are pivotal for the activation
and function of adaptive natural killer cells in human cytomegalovirus
infection (9).
