Ezrin/radixin/moesin: versatile controllers of signaling molecules and of the cortical cytoskeleton.


Ezrin, radixin and moesin (ERM) proteins are widely distributed proteins located in the cellular cortex, in microvilli and adherens junctions. They feature an N-terminal membrane binding domain linked by an alpha-helical domain to the C-terminal actin-binding domain. In the dormant state, binding sites in the N-terminal domain are masked by interactions with the C-terminal region. The alpha-helical domain also contributes to masking of binding sites. A specific sequence of signaling events results in dissociation of these intramolecular interactions resulting in ERM activation. ERM molecules have been implicated in mediating actin-membrane linkage and in regulating signaling molecules. They are involved in cell membrane organization, cell migration, phagocytosis and apoptosis, and may also play cell-specific roles in tumor progression. Their precise involvement in these processes has yet to be elucidated.
