Background
CD5, one of the earliest markers used to identify T cells, is a 67 kD transmembrane molecule that is constitutively expressed on all T cells and is a negative regulator of lymphocyte function. T-cell surface glycoprotein CD5 is also known as Lymphocyte antigen T1/Leu-1 and LEU1. CD5 is also a negative regulator of thymus cell stimulation. Lack of CD5 promotes positive selection of poorly selected thymocytes and increases negative selection of high-affinity clones. Along with its negative effect on T cell stimulation, CD5 was shown to diminish activation-induced cell death (AICD) through its interaction with casein kinase 2 (CK2).
