Adaptor proteins are essential components of T cell receptor (TCR) signaling cascades regulating gene transcription and cytoskeletal reorganization. The molecular adaptor adhesion- and degranulation-promoting adaptor protein (ADAP), also known as Fyn binding protein (FYB) or Slp-76-associated protein of 130 kilodaltons (SLAP-130), interacts with a number of signaling intermediates including Slp-76, the Src family tyrosine kinase Fyn, vasodilator-stimulated phosphoprotein (VASP), and the actin-nucleating protein WASP. Recently ADAP was shown genetically to positively regulate T cell activation, TCR-induced integrin clustering, and T cell adhesion. The mechanism by which ADAP couples TCR stimulation to integrin clustering remains unclear; however, studies of ADAP, the exchange factor Vav1, and WASP suggest that TCR and integrin clustering may be controlled by distinct signaling pathways.
