Abstact

ESCRT-II, a complex that sorts ubiquitinated membrane proteins to lysosomes, localizes to endosomes through interaction between the Vps36 subunit's GLUE domain and phosphatidylinositides (PIs). In yeast, a ubiquitin (Ub)-interacting NZF domain is inserted in Vps36 GLUE, whereas its mammalian counterpart, Eap45 GLUE, lacks the NZF domain. In the Eap45 GLUE-Ub complex structure, Ub binds far from the proposed PI-binding site of Eap45 GLUE, suggesting their independent binding.
