Structural highlights

Disease

[NFU1_HUMAN] Fatal multiple mitochondrial dysfunction syndrome;Fatal infantile encephalopathy-pulmonary hypertension syndrome. Multiple mitochondrial dysfunctions syndrome 1 (MMDS1) [MIM:605711]: A severe disorder of systemic energy metabolism, resulting in weakness, respiratory failure, lack of neurologic development, lactic acidosis, hyperglycinemia and early death. Some patients show failure to thrive, pulmonary hypertension, hypotonia and irritability. Biochemical features include severe combined deficiency of the 2-oxoacid dehydrogenases, defective lipoic acid synthesis and reduction in activity of mitochondrial respiratory chain complexes. Note=The disease is caused by mutations affecting the gene represented in this entry.^{[1] [2]}

Function

[NFU1_HUMAN] Iron-sulfur cluster scaffold protein which can assemble [4Fe-2S] clusters and deliver them to target proteins.^[3]
