General Information
Term multivesicular body ID (Ontology) GO:0005771 (Gene Ontology)
Definition A type of endosome in which regions of the limiting endosomal membrane invaginate to form internal vesicles; membrane proteins that enter the internal vesicles are sequestered from the cytoplasm.[ PubMed:11566881 PubMed:16533950 ]
Also Known As "multivesicular endosome" ; "MVB" ; "MVE"
