Abstact

The ESCRT-I and ESCRT-II complexes help sort ubiquitinated proteins into vesicles that accumulate within multivesicular bodies (MVBs). Crystallographic and biochemical analyses reveal that the GLUE domain of the human ESCRT-II EAP45 (also called VPS36) subunit is a split pleckstrin-homology domain that binds ubiquitin along one edge of the beta-sandwich. The structure suggests how human ESCRT-II can couple recognition of ubiquitinated cargoes and endosomal phospholipids during MVB protein sorting.
