Escrt machinery
WebJan 16, 2014 · ESCRT machinery participates in important cellular membrane remodeling events, such as cytokinesis and multivesicular body biogenesis (MVB), organizing into three general sets of subcomplexes. One set includes ESCRT-0, -I, and -II, which interact directly with cargo or scaffold proteins to direct assembly of downstream ESCRT complexes. WebNov 18, 2024 · The ESCRT machinery is an ancient system for membrane remodeling and scission; in eukaryotes it includes five distinct subcomplexes: ESCRT-0, I, II, III, and the AAA ATPase Vps4 . The ESCRT pathway drives diverse cellular processes, such as multivesicular body (MVB) formation, nuclear pore complex (NPC) quality control, virus …
