Multivesicular body subunit 12, isoform A; Ubiquitin binding. It is involved in the biological process described with: virus maturation; viral budding; receptor catabolic process; endosome to lysosome transport via multivesicular body sorting pathway; regulation of epidermal growth factor receptor signaling pathway.

Vesicle trafficking 1; ATPase activator activity. It is involved in the biological process described with: endosome transport via multivesicular body sorting pathway; late endosome to vacuole transport via multivesicular body sorting pathway.

Charged multivesicular body protein 2b (CHMP2B) encodes an ESCRT-III component. It plays an important role in the generation of multivesicular bodies in the endosomal lysosomal pathway. It is also considered to play an important role in autophagosome maturation.

Charged multivesicular body protein 1 (Chmp1) encodes a component of ESCRT-III, a conserved protein complex that mediates downregulation of activated transmembrane receptors through formation of the multivesicular body from the endosome. It binds to the product of Vps4, promoting the dissociation and recycling of ESCRT-III components to the cytoplasm.

Vacuolar protein sorting 2 (Vps2) encodes an ion channel involved in the transmembrane transport of potassium.

Vacuolar protein-sorting-associated protein 25; Component of the ESCRT-II complex (endosomal sorting complex required for transport II), which is required for multivesicular body (MVB) formation and sorting of endosomal cargo proteins into MVBs. The MVB pathway mediates delivery of transmembrane proteins into the lumen of the lysosome for degradation. The ESCRT-II complex is probably involved in the recruitment of the ESCRT-III complex (By similarity). Seems to function as a tumor suppressor by regulating Notch trafficking, hence preventing non-autonomous overproliferation. May be invo [...]

Vacuolar protein-sorting-associated protein 36; Component of the ESCRT-II complex (endosomal sorting complex required for transport II), which is required for multivesicular body (MVB) formation and sorting of endosomal cargo proteins into MVBs. The MVB pathway mediates delivery of transmembrane proteins into the lumen of the lysosome for degradation. The ESCRT-II complex is probably involved in the recruitment of the ESCRT-III complex (By similarity). ESCRT-II interacts, through the Vps36 subunit, with bicoid mRNA. This interaction is required for the anterior localization of bicoid m [...]

GH13992p; Shrub (shrb) encodes Shrub encodes Vps32/Snf7, a filament-forming subunit of the ESCRT-III complex involved in inward membrane budding. It regulates multiple cellular processes involving ESCRTs activity including multivesicular body biogenesis, cytokinesis, membrane repair and regulation of membrane associated signaling.

Charged multivesicular body protein 5; Probable peripherally associated component of the endosomal sorting required for transport complex III (ESCRT-III) which is involved in multivesicular bodies (MVBs) formation and sorting of endosomal cargo proteins into MVBs. MVBs contain intraluminal vesicles (ILVs) that are generated by invagination and scission from the limiting membrane of the endosome and are delivered to lysosomes enabling degradation of membrane proteins (By similarity). Specifically down-regulates Notch signaling activity in the germarium, probably by facilitating Notch en [...]
