J.Am.Chem.Soc., 131:14196-14197, 2009 Cited by PubMed Abstract: Copper trafficking proteins, including the chaperone Atox1 and the P(1B)-type ATPase ATP7B, have been implicated in cellular resistance to the anticancer drug cisplatin. We have determined two crystal structures of cisplatin-Atox1 adducts that reveal platinum coordination by the conserved CXXC copper-binding motif. Direct interaction of cisplatin with this functionally relevant site has significant implications for understanding the molecular basis for resistance mediated by copper transport pathways.
