Dissertation summary The role of membrane microdomains and transmembrane adaptor proteins PRR7 and SCIMP in the regulation of immunoreceptor signaling Matouš Hrdinka How do the plasma membrane microdomains and transmembrane adaptor proteins (TRAPs) influence the outcome of immunoreceptor signaling? These have been the important questions of molecular immunology. In spite of the years of intensive research, these problems remain incompletely understood. The plasma membrane is a highly dynamic heterogeneous bilayer spontaneously organized into microdomains of various size, composition, and lifetime. The lipid rafts are one example of such microdomains and have been implicated in many biological processes, including immunoreceptor signaling. Because rafts are enriched in many signaling proteins, they are believed to function as platforms for signal initiation and propagation. The TRAPs are important organizers and regulators of immunoreceptor signaling. For example, LAT is indispensable in T cell receptor (TCR) signaling and T cell development, PAG for the regulation of Src family tyrosine kinases (SFKs), and NTAL is a multifunctional negative and positive regulator. The presence of these TRAPs in lipid rafts seems to be crucial for their functions, however, is still a matter of debate. Moreover, other so far...
