T cells respond to antigen through multiple signals, many of which are driven by proteins that coassociate at the cell membrane. SLP-76 is a primary signaling molecule that is recruited by the integral membrane protein LAT, and together they initiate several signaling pathways. Yoder et al. show that GADS, a small adaptor protein, is critical in mediating this association and thus has a significant impact on T cell development. Thymocytes from mice deficient in the expression of GADS displayed defects in cellular proliferation, as well as in positive and negative selection. By connecting SLP-76 and LAT, GADS facilitates important SLP-76-dependent signals at different stages of T cell development.
