The activation of protein tyrosine kinases is a critical event in T cell antigen receptor (TCR)-mediated signaling. One substrate of the TCR-activated protein tyrosine kinase pathway is a 76-kDa protein (SLP-76) that associates with the adaptor protein Grb2. Northern analysis demonstrates that pp76 mRNA is expressed solely in peripheral blood leukocytes, thymus, and spleen; and in human T cell, B cell and monocytic cell lines. In vitro translation of pp76 cDNA gives rise to a single product of 76 kDa that associates with a GST/Grb2 fusion protein, demonstrating a direct association between these two molecules. Results demonstrate that this novel protein is likely to play an important role in TCR-mediated intracellular signal transduction (1). It has been shown that both SLP-76 and ZAP70 co-immunoprecipitate with Shb in Jurkat T cells and that Shb and Vav co-immunoprecipitate when cotransfected in COS cells. Results indicate that upon TCR stimulation, Shb is targeted to these lipid rafts where Shb aids in recruiting the SLP-76-Gads-Vav complex to the T cell receptor zeta-chain and ZAP70 (2). Tyrosine phosphorylation of SLP-76 at position 113 or 128 was sufficient for it to associate with the N-terminal SH2 of p85. This data suggest that SLP-76 may play a role in PI3K signaling pathways (3).
