Abstract excerpt
The linker for activation of T-cells (LAT) is a palmitoylated integral membrane adaptor protein that resides in lipid membrane rafts and contains nine consensus putative tyrosine phosphorylation sites, several of which have been shown to serve as SH2 binding sites. Upon T-cell antigen receptor (TCR/CD3) engagement, LAT is phosphorylated by protein tyrosine kinases (PTK) and binds to the adaptors Gads and Grb2, as...
