  • Function

    This protein is one of the nuclear-coded polypeptide chains of cytochrome c oxidase, the terminal oxidase in mitochondrial electron transport.
  • Tissue specificity

    Highly expressed in lung.
  • Involvement in disease

    Defects in COX4I2 are the cause of exocrine pancreatic insufficiency dyserythropoietic anemia and calvarial hyperostosis (EPIDACH) [MIM:612714]. Patients present with pancreatic insufficiency, intestinal malabsorption, failure to thrive, and anemia soon after birth.
  • Sequence similarities
