Predicted to enable cysteine desulfurase activity and protein homodimerization activity. Involved in iron incorporation into metallo-sulfur cluster. Located in mitochondrial matrix and nucleus. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in combined oxidative phosphorylation deficiency. Orthologous to human NFS1 (NFS1 cysteine desulfurase). [provided by Alliance of Genome Resources, Apr 2022]
