== Function ==
 
'''CD3''' (or '''Cluster of Differentiation 3''') is a T-cell co-receptor.  The CD3 is composed of γ, δ and two ε chains.  These 4 chains associate with the T-cell receptor (TCR) and a ζ chain to form an activation signal in T lymphocytes.  CD3 assembles as 3 pairs of dimers: εγ, εδ and ζζ.  The intracellular domain of CD3 contains a single immunorecetor tyrosine-based activation motif (ITAM).  Drugs which bind to CD3 are tested as immunorepressants.
