Shalek1,2,3*‡ The disordered adapter protein linker for activation of T cells (LAT) propagates T cell receptor signaling. To interrogate how LAT coordinates multiple downstream pathways, we developed a single-cell screening approach, identifying widespread functional segments including protein interaction motifs and blocks of negative charge. Regardless of their position in LAT, individual segments generally conferred defects across all downstream signaling pathways. …
