T Cell Antigen Receptor CD3 Complex

Molecule composed of the non-covalent Association of the T-Cell Antigen Receptor (Receptors, Antigen, T-Cell) with the CD3 Complex (Antigens, CD3). This Association is required for the surface expression and function of both components. The molecule consists of up to seven chains: either the alpha/beta or gamma/delta chains of the T-Cell Receptor, and four or five chains in the CD3 Complex.
