Protein Structure
UniProt Annotation
Function Proposed to be involved in specific functions of the ESCRT machinery. Is required for efficient abscission during cytokinesis, but not for HIV-1 budding. The involvement in the MVB pathway is not established. Involved in recruiting VPS4A and/or VPS4B to the midbody of dividing cells. {ECO:0000269PubMed:19129479, ECO:0000269PubMed:19129480}.
Subcellular Localization Cytoplasmic vesicle {ECO:0000269PubMed:19129479, ECO:0000269PubMed:19129480}. Note=Localizes to the midbody of dividing cells.
