This domain is found at the N-terminal end of COMM domain-containing protein 9 from humans and similar proteins from vertebrates. COMMD9 contains a conserved and unique motif termed the COMM (copper metabolism gene MURR1, Pfam:PF07258) domain at the C-terminal, which functions as an interface for protein-protein interactions. This entry represents the N-terminal domain, which shows a globular structure that consists of a six-helix bundle with a meander topology [1,2].	Domain
