Stimulation of activated T cells with interleukin-2 (IL-2) results in the tyrosine phosphorylation of several intracellular proteins. The present studies demonstrate that IL-2 stimulation induces phosphorylation of the src homology 2 domain-containing protein, p52shc, on both tyrosine and serine residues. The level of p52shc phosphorylation was maximal within 5 min after growth factor addition and declined gradually thereafter. In addition, anti-Shc immunoprecipitates from IL-2-stimulated T cells contained a co-precipitating protein tyrosine kinase (PTK) activity that phosphorylated p52shc on tyrosine residues in immune complex kinase assays. These results demonstrate that p52shc is an early substrate for IL-2 receptor-coupled PTK activity(s) and suggest that this protein may be involved in the transduction of PTK-dependent regulatory signals in IL-2-stimulated T cells.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013602	T-Lymphocytes, Cytotoxic	Immunized T-lymphocytes which can directly destroy appropriate target cells. These cytotoxic lymphocytes may be generated in vitro in mixed lymphocyte cultures (MLC), in vivo during a graft-versus-host (GVH) reaction, or after immunization with an allograft, tumor cell or virally transformed or chemically modified target cell. The lytic phenomenon is sometimes referred to as cell-mediated lympholysis (CML). These CD8-positive cells are distinct from NATURAL KILLER CELLS and NATURAL KILLER T-CELLS. There are two effector phenotypes: TC1 and TC2.
