A Mechanism of Cell Survival

Abstract

Death receptors such as Fas are present in a variety of organs including liver and play an important role in homeostasis. What prevents these harmful receptors from forming homooligomers, clustering, and initiating the apoptotic pathway is not known. Here, we report the discovery of a cell survival mechanism by which Met, a growth factor receptor tyrosine kinase, directly binds to and sequesters the death receptor Fas in hepatocytes. This interaction prevents Fas self-aggregation and Fas ligand binding, thus inhibiting Fas activation and apoptosis. Our results describe a direct link between growth factor tyrosine kinase receptors and death receptors to establish a novel paradigm in growth regulation.
