CC   -!- FUNCTION: Probable core component of the endosomal sorting required for
CC       transport complex III (ESCRT-III) which is involved in multivesicular
CC       bodies (MVBs) formation and sorting of endosomal cargo proteins into
CC       MVBs. MVBs contain intraluminal vesicles (ILVs) that are generated by
CC       invagination and scission from the limiting membrane of the endosome
CC       and mostly are delivered to lysosomes enabling degradation of membrane
CC       proteins, such as stimulated growth factor receptors, lysosomal enzymes
CC       and lipids (By similarity). {ECO:0000250|UniProtKB:Q9H444}.
CC   -!- SUBUNIT: Probable core component of the endosomal sorting required for
CC       transport complex III (ESCRT-III). ESCRT-III components are thought to
CC       multimerize to form a flat lattice on the perimeter membrane of the
CC       endosome (By similarity). {ECO:0000250|UniProtKB:Q9H444}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol
CC       {ECO:0000250|UniProtKB:Q9H444}. Late endosome membrane
CC       {ECO:0000250|UniProtKB:Q9H444}; Peripheral membrane protein
CC       {ECO:0000250|UniProtKB:Q9H444}. Midbody {ECO:0000250|UniProtKB:Q9H444}.
CC   -!- SIMILARITY: Belongs to the SNF7 family. {ECO:0000305}.
