PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • a twin CX9C motif and a Cys-Cys motif at the N terminus involved in copper binding
  • a CHCH motif of about 40 AAs plus an unstructured, flexible N-terminal tail of about 15 AAs
  • a cysteine rich motif
  • six conserved Cys residues
  • two additional cysteine residues also conserved in metallothionein 1
    • secondary structure
  • the inner disulfide of COX17 is the essential one for producing a single conformational state of the protein, playing a key structural role in the CHCH fold, whereas the outer disulfide bond defines the copper binding site structural environment of COX17

    basic FUNCTION
  • copper chaperone for cytochrome-c oxidase, involved in targeting copper to mitochondria
  • copper-binding protein, which facilitates incorporation of copper ions into Cu(A) site of cytochrome c oxidase
  • key mitochondrial copper chaperone involved in the assembly of cytochrome c oxidase (COX)
  • can play a role within intermembrane space for tightly controling the copper concentration, similar to what it has been found in the cytoplasm where several systems of cellular copper transport, involving also ATOX1, have been discovered
  • mitochondrial copper chaperone responsible for supplying copper ions, through the assistance of SCO1, SCO2, and COX11, to cytochrome c oxidase
