Iron-sulfur cluster transfer protein involved in the assembly of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) (PubMed:19752196). May deliver one or more Fe-S clusters to complex I subunits (PubMed:19752196). . This is the function of ENSG00000151413 (NUBPL, NUBP iron-sulfur cluster assembly factor, mitochondrial).
