  • Function

    Probably plays an important role in metabolic homeostasis in mitochondria. May function as a nuclear-cytoplasmic shuttling protein that binds transcription factor RELA/NFKB3 in the nucleus and exports it to the cytoplasm. Suppresses p53-induced apoptosis by preventing nuclear localization of RELA.
  • Tissue specificity

    Ubiquitously expressed.
  • Involvement in disease

    Defects in ETHE1 are a cause of ethylmalonic encephalopathy (EE) [MIM:602473]. EE is an autosomal recessive disorder characterized by neurodevelopmental delay and regression, recurrent petechiae, acrocyanosis, diarrhea, leading to death in the first decade of life. It is also associated with persistent lactic acidemia and ethylmalonic and methylsuccinic aciduria.
  • Sequence similarities

    Belongs to the metallo-beta-lactamase superfamily. Glyoxalase II family.
  • Cellular localization

    Cytoplasm. Nucleus. Mitochondrion matrix. According to PubMed:12398897, it is cytoplasmic and nuclear. According to PubMed:14732903, it is found in the mitochondrial matrix.
