CC -!- FUNCTION: NADPH-dependent reductase which is a central component of the
CC cytosolic iron-sulfur (Fe-S) protein assembly (CIA) machinery.
CC Transfers electrons from NADPH via its FAD and FMN prosthetic groups to
CC the [2Fe-2S] cluster of CIAPIN1, another key component of the CIA
CC machinery. In turn, this reduced cluster provides electrons for
CC assembly of cytosolic iron-sulfur cluster proteins. It can also reduce
CC the [2Fe-2S] cluster of CISD1 and activate this protein implicated in
CC Fe/S cluster repair. {ECO:0000256|HAMAP-Rule:MF_03178}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=NADPH + 2 oxidized [2Fe-2S]-[protein] = H(+) + NADP(+) + 2
CC reduced [2Fe-2S]-[protein]; Xref=Rhea:RHEA:67716, Rhea:RHEA-

CC -!- SUBUNIT: Interacts with CIAPIN1; as part of the cytosolic iron-sulfur
CC (Fe-S) protein assembly (CIA) machinery. {ECO:0000256|HAMAP-
CC Rule:MF_03178}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, perinuclear region {ECO:0000256|HAMAP-

CC -!- SIMILARITY: Belongs to the NADPH-dependent diflavin oxidoreductase
CC NDOR1 family. {ECO:0000256|HAMAP-Rule:MF_03178}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the flavoprotein
CC pyridine nucleotide cytochrome reductase family. {ECO:0000256|HAMAP-
CC Rule:MF_03178}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the flavodoxin
CC family. {ECO:0000256|HAMAP-Rule:MF_03178}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_03178}.
