The metallothionein MT3 is able to bind 12 copper(I) atoms when fully saturated (Roschitzki et al. 2002). Initially, 4 copper(I) atoms bind to each of the alpha and beta domains followed by the binding of 4 more copper(I) atoms. As inferred from the mouse homolog, MT3 exhibits a Cu-thionein character stronger than that of the MT1 and MT2 isoforms and it displays a high capacity to bind Cu+ provided that this occurs in a non-oxidative milieux.
