Gloss: Adaptor proteins, which contain multiple intermolecular interaction domains, are critical intermediates in T cell receptor (TCR) signaling cascades leading to transcriptional and cytoskeletal changes. Recently, the 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), was demonstrated by genetic methods to couple TCR stimulation to integrin clustering and T cell adhesion.
