| - | '''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. | + | '''CD3''' (or '''Cluster of Differentiation 3''') is a T-cell co-receptor. The CD3 is composed of γ, δ and two ε chains.
