Abstract/OtherAbstract:
Fas interaction at the plasma membrane with its lipid and protein environment plays a crucial role in the early steps of Fas signalling induced by Fas ligand binding. Particularly, Fas localisation in the raft nanodomains, ezrin-mediated interaction with the actin cytoskeleton and subsequent internalization are critical steps in Fas-mediated cell death. We identified a lysine-rich region (LRR) in the cytoplasmic, membrane-proximal region of Fas as a key determinant modulating these initial events. Through a genetic approach, we demonstrate that Fas LRR represents another signal additional to palmitoylation targeting Fas to the raft nanodomains, and modulates Fas interaction with the cytoskeleton.
