Target

  • Function

    Component of the ESCRT-I complex, a regulator of vesicular trafficking process. Binds to ubiquitinated cargo proteins and is required for the sorting of endocytic ubiquitinated cargos into multivesicular bodies (MVBs). Mediates the association between the ESCRT-0 and ESCRT-I complex. Required for completion of cytokinesis; the function requires CEP55. May be involved in cell growth and differentiation. Acts as a negative growth regulator. Involved in the budding of many viruses through an interaction with viral proteins that contain a late-budding motif P-[ST]-A-P. This interaction is essential for viral particle budding of numerous retroviruses.

  • Tissue specificity

    Heart, brain, placenta, lung, liver, skeletal, kidney and pancreas.

  • Sequence similarities

    Belongs to the ubiquitin-conjugating enzyme family. UEV subfamily.
    Contains 1 SB (steadiness box) domain.
    Contains 1 UEV (ubiquitin E2 variant) domain.

  • Domain

    The UEV domain is required for the interaction of the complex with ubiquitin. It also mediates the interaction with PTAP/PSAP motifs of HIV-1 P6 protein and human spumaretrovirus Gag protein.
    The coiled coil domain may interact with stathmin.
    The UEV domain binds ubiquitin and P-[ST]-A-P peptide motif independently.

  • Post-translational
    modifications

    Monoubiquitinated at multiple sites by LRSAM1 and by MGRN1. Ubiquitination inactivates it, possibly by regulating its shuttling between an active membrane-bound protein and an inactive soluble form. Ubiquitination by MGRN1 requires the presence of UBE2D1.

  • Cellular localization

    Cytoplasm. Membrane. Nucleus. Late endosome membrane. Mainly cytoplasmic. Membrane-associated when active and soluble when inactive. Depending on the stage of the cell cycle, detected in the nucleus. Colocalized with CEP55 in the midbody during cytokinesis.
