Background：CD3epsilon is a 20 kD chain of the CD3/T cell receptor （TCR） complex, which is composed of two CD3epsilon, one CD3gamma, one CD3delta, one CD3ζ （CD247）, and a T cell receptor （a/b or gamma/delta） heterodimer. It is found on all mature T lymphocytes, NK T cells, and some thymocytes. CD3, also known as T3, is a member of the immunoglobulin superfamily that plays a role in antigen recognition, signal transduction, and T cell activation.
