he initial signaling event following the engagement of T and B cell antigen receptors (TCR and BCR, respectively) is the activation of Src family protein tyrosine kinases (PTKs) such as Lck and Fyn in T cells and Lyn in B cells (reviewed in Refs. 1, 2). These PTKs phosphorylate tyrosine-containing i

β¦ Synopsis
Adaptor molecules, proteins that possess no intrinsic enzymatic function, but which mediate protein-protein interactions, have a critical role in integrating signal transduction pathways following engagement of cell-surface receptors. Several newly described adaptor molecules have been shown to serve important functions in the regulation of signaling events initiated by lymphocyte antigen receptors. Understanding how these adaptor proteins function to modulate signaling cascades will provide important insights into the complex biology of lymphocyte activation.

Immunological interest in small GTPases has focused for some years almost exclusively on the role of Ras in promoting lymphocyte activation and development. A new concept in this field is that GTPases are linked to multiple biochemical effector signalling pathways and are consequently able to regula
