Abstract

Receptor tyrosine kinases (RTKs) transmit signals to the cell nucleus via the MAP kinase (MAPK) cascade, using specific molecules to link the activated receptors to the MAPK cascade activator, Ras. We have identified a component of the FGF receptor (FGFR) signal transduction pathway, Downstream of FGFR (Dof). Dof is an intracellular protein that is essential for signal transmission by the FGFR and acts downstream of the receptor and upstream of Ras. Unlike other signaling molecules that act downstream of RTKs, Dof is not expressed ubiquitously but is present exclusively in cells that express FGFRs. Dof is needed in these cells for activation of the MAPK cascade via FGF signaling, but not for activation via other RTK ligands. Dof therefore appears to be committed exclusively to FGFR-mediated signal transduction.
