Tcell surface glycoprotein CD3 delta & CD3 epsilon chain, also known as CD3D & CD3E or CD3D&CD3E respectively, are singlepass type I membrane proteins. CD3D, together with CD3 epsilon(CD3E) , CD3gamma and CD3zeta, and the Tcell receptor alpha/beta and gamma/delta heterodimers, forms the T cell receptorCD3 complex. T cell receptorCD3 complex plays an important role in coupling antigen recognition to several intracellular signaltransduction pathways. - Proteine/Peptide
