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