CC -!- FUNCTION: Involved in late steps of the endosomal multivesicular bodies
CC (MVB) pathway. Recognizes membrane-associated ESCRT-III assemblies and
CC catalyzes their disassembly, possibly in combination with membrane
CC fission. Redistributes the ESCRT-III components to the cytoplasm for
CC further rounds of MVB sorting. 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. It is required for
CC proper accomplishment of various processes including the regulation of
CC endosome size, primary cilium organization, mitotic spindle
CC organization and chromosome segregation, and nuclear envelope sealing
CC and spindle disassembly during anaphase (By similarity). In conjunction
CC with the ESCRT machinery also appears to function in topologically
CC equivalent membrane fission events, such as the terminal stages of
CC cytokinesis. Involved in cytokinesis: retained at the midbody by
CC ZFYVE19/ANCHR and CHMP4C until abscission checkpoint signaling is
CC terminated at late cytokinesis. It is then released following
CC dephosphorylation of CHMP4C, leading to abscission. VPS4A/B are
CC required for the exosomal release of SDCBP, CD63 and syndecan (By
CC similarity). Critical for normal erythroblast cytokinesis and correct
CC erythropoiesis (By similarity). {ECO:0000250|UniProtKB:Q9UN37}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.6;
CC Evidence={ECO:0000250|UniProtKB:O75351};
CC -!- SUBUNIT: Proposed to be monomeric or homodimeric in nucleotide-free
CC form and to oligomerize upon binding to ATP to form two stacked
CC hexameric or heptameric rings with a central pore through which ESCRT-
CC III substrates are translocated in an ATP-dependent manner (By
CC similarity). Interacts with CHMP1A, CHMP1B, CHMP2A, CHMP2B, CHMP3,
CC CHMP4A, CHMP4B, CHMP4C and CHMP6. Interacts with VPS4B; the interaction
CC suggests a heteromeric assembly with VPS4B. Interacts with SPAST.
CC Interacts with IST1. Interacts with ZFYVE19/ANCHR; leading to retain it
CC at midbody (By similarity). {ECO:0000250,
CC ECO:0000250|UniProtKB:Q9UN37}.
CC -!- SUBCELLULAR LOCATION: Late endosome membrane
CC {ECO:0000250|UniProtKB:Q8VEJ9}; Peripheral membrane protein
CC {ECO:0000250|UniProtKB:Q8VEJ9}. Midbody {ECO:0000250|UniProtKB:Q9UN37}.
CC Cytoplasm, cytoskeleton, spindle {ECO:0000250|UniProtKB:Q9UN37}.
CC Note=Membrane-associated in the prevacuolar endosomal compartment.
CC Localizes to the midbody of dividing cells, interaction with
CC ZFYVE19/ANCHR mediates retention at midbody. Localized in two distinct
CC rings on either side of the Flemming body.
CC {ECO:0000250|UniProtKB:Q9UN37}.
CC -!- DOMAIN: The MIT domain serves as an adapter for ESCRT-III proteins. It
CC forms an asymmetric three-helix bundle that binds amphipathic MIM (MIT
CC interacting motif) helices along the groove between MIT helices 2 and 3
CC present in a subset of ESCRT-III proteins thus establishing the
CC canonical MIM-MIT interaction. In an extended conformation along the
CC groove between helices 1 and 3, also binds to a type-2 MIT interacting
CC motif (MIM2) (By similarity). {ECO:0000250|UniProtKB:O75351}.
CC -!- SIMILARITY: Belongs to the AAA ATPase family. {ECO:0000305}.
