{"abstract":[{"lang":"eng","text":"Clathrin-mediated vesicle trafficking plays central roles in post-Golgi transport. In yeast (Saccharomyces cerevisiae), the AP-1 complex and GGA adaptors are predicted to generate distinct transport vesicles at the trans-Golgi network (TGN), and the epsin-related proteins Ent3p and Ent5p (collectively Ent3p/5p) act as accessories for these adaptors. Recently, we showed that vesicle transport from the TGN is crucial for yeast Rab5 (Vps21p)-mediated endosome formation, and that Ent3p/5p are crucial for this process, whereas AP-1 and GGA adaptors are dispensable. However, these observations were incompatible with previous studies showing that these adaptors are required for Ent3p/5p recruitment to the TGN, and thus the overall mechanism responsible for regulation of Vps21p activity remains ambiguous. Here, we investigated the functional relationships between clathrin adaptors in post-Golgi-mediated Vps21p activation. We show that AP-1 disruption in the ent3Δ5Δ mutant impaired transport of the Vps21p guanine nucleotide exchange factor Vps9p transport to the Vps21p compartment and severely reduced Vps21p activity. Additionally, GGA adaptors, the phosphatidylinositol-4-kinase Pik1p and Rab11 GTPases Ypt31p and Ypt32p were found to have partially overlapping functions for recruitment of AP-1 and Ent3p/5p to the TGN. These findings suggest a distinct role of clathrin adaptors for Vps21p activation in the TGN–endosome trafficking pathway."}],"oa":1,"year":"2023","main_file_link":[{"url":"https://doi.org/10.1101/2023.03.27.534325","open_access":"1"}],"language":[{"iso":"eng"}],"day":"01","author":[{"last_name":"Nagano","first_name":"Makoto","full_name":"Nagano, Makoto"},{"first_name":"Kaito","last_name":"Aoshima","full_name":"Aoshima, Kaito"},{"full_name":"Shimamura, Hiroki","first_name":"Hiroki","last_name":"Shimamura"},{"first_name":"Daria E","last_name":"Siekhaus","orcid":"0000-0001-8323-8353","full_name":"Siekhaus, Daria E","id":"3D224B9E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Junko Y.","last_name":"Toshima","full_name":"Toshima, Junko Y."},{"full_name":"Toshima, Jiro","last_name":"Toshima","first_name":"Jiro"}],"article_number":"jcs261448","article_processing_charge":"No","title":"Distinct role of TGN-resident clathrin adaptors for Vps21p activation in the TGN-endosome trafficking pathway","intvolume":"       136","citation":{"ieee":"M.
