Abstract
In previous studies we demonstrated that the antigen receptor complex on murine T cells is phosphorylated after antigen or mitogen activation. After the clonotypic structures bind antigen, the invariant subunits or CD3 molecules are the target of dual kinase activation. The antigen receptor CD3-gamma-chain subunit is phosphorylated on serine residues by activated protein kinase C and the p21 subunit is phosphorylated by a tyrosine kinase. Herein we demonstrate that another mechanism of receptor activation by the stimulatory monoclonal antibody 145-2C11, which binds the CD3-epsilon chain, results in a similar pattern of kinase activation and receptor phosphorylation.This publication has 17 references indexed in Scilit:
