Spatial organization of FGF receptor 1 by multimeric ligand assemblies

Fibroblast growth factor receptor 1 (FGFR1) is a receptor tyrosine kinases that together with extracellular fibroblast growth factors (FGFs) transduce signals through the plasma membrane. The FGFRs-FGFs signaling cascades regulate a variety of biological processes, including angiogenesis, embryogenesis, tissue repair and metabolism. Importantly, the aberrant FGFRs-FGFs signaling axis leads to the severe developmental disorders and cancer.

AIM OF THE PROJECT:

The goal of this project is to establish how plasma membrane organization of FGFR1 affects receptor function. By employing different FGFR1 ligands and their configurations in the multimeric ligand assemblies (MLAs), the spatial requirements for FGFR1 activity and internalization will be assessed (Fig. 1). We predict that MLAs will constitute a tool for adjusting FGFR1 activity and thus selective modulation of cell response. FGFR1 dimerization induces FGFR1 internalization. With MLAs we intend to cluster FGFR1 into higher order assemblies to boost receptor endocytosis, which we intend to utilize to enhance selective delivery of cytotoxic drugs into FGFR1 overproducing cancer cells.
