functional studies in several laboratories , including our own , suggest a `` '' division of labor '' '' between the alpha/beta chain heterodimer ( t cell receptor ) and the three other polypeptide chains ( t3 gamma , delta , epsilon ) : the t cell receptor alpha and beta chains together recognize antigen and mhc product on the antigen presenting or target cell and an activating signal is transduced to the cytoplasmatic side of the plasma membrane via the t3 complex .
