T-cell surface glycoprotein CD3 delta & CD3 epsilon chain, also known as CD3D & CD3E or CD3D&CD3E respectively, are single-pass type I membrane proteins. CD3D, together with CD3E, CD3-gamma and CD3-zeta, and the T-cell receptor alpha/beta, and gamma/delta heterodimers, form the T cell receptor-CD3 complex. T cell receptor-CD3 complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. Since CD3 is required for T-Cell activation, drugs and therapeutics targeting CD3 are being researched for diseases like Type 1 diabetes and other autoimmune diseases. For example, Muromonab-CD3, a monoclonal antibody targeting the CD3 receptor, is an immunosuppressant drug to reduce acute rejection in patients with organ transplants.
