== Disease ==
[https://www.uniprot.org/uniprot/ABCB7_HUMAN ABCB7_HUMAN] X-linked sideroblastic anemia and spinocerebellar ataxia. The disease is caused by variants affecting the gene represented in this entry.
== Function ==
[https://www.uniprot.org/uniprot/ABCB7_HUMAN ABCB7_HUMAN] 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 (PubMed:10196363, PubMed:17192393, PubMed:33157103). Moreover, through a functional complex formed of ABCB7, FECH and ABCB10, also plays a role in the cellular iron homeostasis, mitochondrial function and heme biosynthesis (PubMed:30765471). In cardiomyocytes, regulates cellular iron homeostasis and cellular reactive oxygen species (ROS) levels through its interaction with COX4I1 (By similarity). May also play a role in hematopoiesis (By similarity).[UniProtKB:Q61102][UniProtKB:Q704E8]<ref>PMID:10196363</ref> <ref>PMID:17192393</ref> <ref>PMID:30765471</ref> <ref>PMID:33157103</ref>
