| abstractText | In addition to the alpha and beta chains of the MHC class II restricted antigen receptor, monoclonal anti-receptor antibodies coprecipitate four polypeptides that appear to be noncovalently associated with the alpha-beta dimer of murine T cells. Included in the murine T cell antigen receptor complex are two glycoproteins of 25 kd (gamma) and 21 kd (delta) and two nonglycosylated polypeptides of 26 kd (epsilon) and 16 kd (zeta). The epsilon chain appears to possess an intrachain disulfide bond and zeta exists in the complex as a disulfide-linked homodimer. The delta chain is phosphorylated on a serine residue in response to T cell activation with antigen. In contrast, both delta and epsilon are phosphorylated in response to treatment of the T cells with phorbol 12-myristate 13-acetate. These polypeptides may play a role in the transduction of the signal(s) in T cell activation. |
