Exports glutathione-coordinated iron-sulfur clusters such as [2Fe-2S]-(GS)4 cluster from the mitochondria to the cytosol in an ATP-dependent manner allowing the assembly of the cytosolic iron-sulfur (Fe/S) cluster-containing proteins and participates in iron homeostasis (By similarity). May play a role in cadmium, zinc and mercury detoxification (PubMed:27734548). (glutathione)4[2Fe(III)-2S] cluster(in) + ATP + H2O = (glutathione)4[2Fe(III)-2S] cluster(out) + ADP + H(+) + phosphate Homodimer. Belongs to the ABC transporter superfamily. ABCB family. Heavy Metal importer (TC 3.A.1.210) subfamily.
