    basic FUNCTION
  • may be playing a key role in the ligand-mediated internalization and down-regulation of the EGF receptor
  • with FAM125B, play a unique role in regulating ESCRT-mediated virus budding
  • tyrosine-phosphorylated protein involved in the aggregation-prone proteins of FAM125B
  • with FAM125B, have various biological roles within ESCRT-I, including their relationships to processes as endocytosis, virus budding, and cellular cytokinesis
  • its function is to promote the downregulation of EGF receptors that are recognized as a cargo protein
  • selective association between MVB12A, MVB12B and VPS37 subunit family members generates distinct ESCRT-I complexes that correlate with different biological activities
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • ESCRT-I complexes contain one copy of each of the four subunit types: UBAP1, MVB12A, MVB12B subunits associate with the core region of the binary TSG101-VPS37 complex through conserved C-terminal sequence elements
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • ubiquitin-binding protein interacting with TSG101
  • UBAP1 is important for MVB12A, MVB12B sorting and degradation of ubiquitylated endosomal cargoes, including EGFR, but not for cytokinesis or retroviral budding
