Transmembrane adaptor protein SIT interacts with SHP2 butalso with Grb2 via two consensus YxN motifs. However, mutation of both Grb2-binding sites does not influence the inhibitory function of SIT. In contrast, mutation of the tyrosine-based signaling motif Y (168) ASV completely abrogates the ability of SIT to inhibit T cell activation. Co-precipitation experiments revealed that the tyrosine kinase p50(csk) could represent the negative regulatory effector molecule that binds to this motif.
