    Abstract

    Mitogenic signaling by G-protein-coupled receptors (GPCRs) involves tyrosine phosphorylation of adaptor proteins and assembly of multiprotein Ras activation complexes. Over the past three years, three types of scaffolds for GPCR-directed complex assembly have been identified: transactivated receptor tyrosine kinases (RTKs), integrin-based focal adhesions, and GPCRs themselves. Nonreceptor tyrosine kinases play an important role in each case. The processes of GPCR desensitization and sequestration via clathrin-coated pits are also involved in signaling through the RTK- and GPCR-based scaffolds.
