The protein contains several distinctive domains, including an N-terminal VHS domain, a phosphatidylinositol 3-phosphate (PtdIns(3)P)-binding FYVE domain and two coiled-coil domains. Here we have investigated the roles of these domains in the subcellular localisation of Hrs. Hrs was found to colocalise extensively with EEA1, an established marker of early endosomes. While the membrane association of EEA1 was abolished in the presence of a dominant negative mutant of the endosomal GTPase Rab5, the localisation of Hrs to early endosomes was Rab5 independent. The VHS-domain was nonessential for the subcellular targeting of Hrs. In contrast, the FYVE domain as well as the second coiled-coil domain, which has been shown to bind to SNAP-25, were required for targeting of Hrs to early endosomes. A small construct consisting of only these two domains was correctly localised to early endosomes, whereas a point mutation (R183A) in the PtdIns(3)P-binding pocket of the FYVE domain inhibited the membrane targeting of Hrs. Thus, like EEA1, the endosomal targeting of Hrs is mediated by a PtdIns(3)P-binding FYVE domain in cooperation with an additional domain. We speculate that binding to PtdIns(3)P and a SNAP-25-related molecule may target Hrs specifically to early endosomes."xsd:string |
