WebThe ESCRT complex (ESCRT-0/-I/-II/-III) machinery plays a vital role in sorting ubiquitinated proteins into vesicles 180 and self-associates at the membrane of endosomes by interacting with its subunit hepatocyte growth factor-regulated tyrosine kinase substrate. WebMVBs contain intraluminal vesicles (ILVs) that are generated by invagination and scission from the limiting membrane of the endosome and mostly are delivered to lysosomes enabling degradation of membrane proteins, such as stimulated growth factor receptors, lysosomal enzymes and lipids.
