  • FunctionE3 ubiquitin-protein ligase which accepts ubiquitin from E2 ubiquitin-conjugating enzymes UBE2L3 and UBE2L6 in the form of a thioester and then directly transfers the ubiquitin to targeted substrates such as LCMT2, thereby promoting their degradation. Induces apoptosis via a p53/TP53-dependent but caspase-independent mechanism. However, its overexpression also produces a decrease of the ubiquitin-dependent stability of BAX, a pro-apoptotic protein, ultimately leading to protection of cell death; But, it is not an anti-apoptotic protein per se.
  • Tissue specificityBroadly expressed, with lowest levels in brain and thymus, and highest levels detectable in heart, ovary and testis.
  • PathwayProtein modification; protein ubiquitination.
  • Sequence similaritiesBelongs to the RBR family. RNF144 subfamily.
    Contains 1 IBR-type zinc finger.
    Contains 2 RING-type zinc fingers.
  • DomainThe RING-type zinc finger domain mediates binding to an E2 ubiquitin-conjugating enzyme (By similarity). The transmembrane domain is essential for translocation to the mitochondria upon induction of apoptosis.
  • Post-translational
  • Cellular localizationMitochondrion membrane. Cytoplasm. Mostly cytosololic, accumulates in submitochondrial domains specifically upon apoptosis induction, in synchrony with BAX activation.
