FunctionInvolved in late steps of the endosomal multivesicular bodies (MVB) pathway. Recognizes membrane-associated ESCRT-III assemblies and catalyzes their disassembly, possibly in combination with membrane fission. Redistributes the ESCRT-III components to the cytoplasm for further rounds of MVB sorting. MVBs contain intraluminal vesicles (ILVs) that are generated by invagination and scission from the limiting membrane of the endosome and mostly are delivered to lysosomes enabling degradation of membrane proteins, such as stimulated growth factor receptors, lysosomal enzymes and lipids. In conjunction with the ESCRT machinery also appears to function in topologically equivalent membrane fission events, such as the terminal stages of cytokinesis and enveloped virus budding (HIV-1 and other lentiviruses).
Tissue specificityUbiquitously expressed.
Sequence similaritiesBelongs to the AAA ATPase family.
Contains 1 MIT domain.
DomainThe MIT domain serves as an adapter for ESCRT-III proteins. It forms an asymmetric three-helix bundle that binds amphipathic MIM (MIT interacting motif) helices along the groove between MIT helices 2 and 3 present in a subset of ESCRT-III proteins thus establishing the canonical MIM-MIT interaction. In an extended conformation along the groove between helices 1 and 3, also binds to a type-2 MIT interacting motif (MIM2).
modificationsPhosphorylated upon DNA damage, probably by ATM or ATR.
Cellular localizationPrevacuolar compartment membrane. Late endosome membrane. Membrane-associated in the prevacuolar endosomal compartment. Localized in HIV-1 particles purified from acutely infected cells.

Predicted band size: 49 kDa
Observed band size: 56 + 58 kDa why is the actual band size different from the predicted?
Additional bands at: 90 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 1 minute
The 56 and 58 kDa band observed are comparable to molecular weights seen with other commercially available antibodies to Human Vacuolar protein sorting-associating protein 4B (VPS4B/MIG1).
