The metallothionein MT2A binds 10 atoms of copper(I). Complexes with up to 12 atoms of Cu+ are observed, however the predominant form appears to be MT2A:10Cu+ (Banci et al. 2010, Chung et al. 2010). Metallothioneins and CuZn-SOD have the highest affinities of cellular proteins for copper(I), but metallothioneins are incapable of removing copper from other cellular enzymes (Banci et al. 2010).
