Predicted to enable ATPase activator activity and protein-folding chaperone binding activity. Predicted to be involved in [2Fe-2S] cluster assembly. Predicted to act upstream of or within protein complex oligomerization. Predicted to be active in mitochondrion. Is expressed in blood island. Used to study sideroblastic anemia. Human ortholog(s) of this gene implicated in sideroblastic anemia. Orthologous to human HSCB (HscB mitochondrial iron-sulfur cluster cochaperone).
