title: Critical role of ESCRT machinery in EGFR recycling.
abstract: The molecular mechanisms of EGFR vesicular trafficking to lysosomes have recently received considerable attention. It is now clear that endosomal sorting complexes required for transport (ESCRTs) are critical for EGFR degradation. Although an increasing number of membrane receptors also undergo recycling via specific pathways, little information is available regarding regulated recycling of EGFR. In this study, we investigated the roles of ESCRTs in EGFR recycling after stimulation with amphiregulin (AR). We used ESCRT small interfering RNA (siRNA) duplexes to demonstrate that AR-induced EGFR intracellular processing involves active sorting to the recycling pathway through specific members of the ESCRT family.
