Fine tuning of tcr signaling by cd5

http://www.grants.gatech.edu/news/biophysics-plays-key-role-immune-system-signaling-response WebThe TCRα/β heterodimer lacks inherent signal transducing activity but associates noncovalently with multiple signal transducing subunits: the CD3γ,-δ and -ε chains, and, in most cases, a ζ chain homodimer. The currently accepted model of αβTCR stoichiometry proposes the following subunit composition: TCRαβ, CD3γε, CD3δε, ζζ.
