The CD2 antigen (LFA-2) is a monomeric 50 kDa glycoprotein. It was formerly described as the sheep red blood cell receptor, causing T-cell rosetting, and has been identified as the ligand for CD58 (LFA-3). It is also a receptor for CD48, CD59 and CD15, which binds to the multimeric form of CD2. CD2 is present on the majority of normal human peripheral blood T lymphocytes and a high percentage of NK cells. It is also expressed by all thymocytes.
