CC -!- FUNCTION: Component of the cytosolic iron-sulfur (Fe/S) protein
CC assembly (CIA) machinery. Required for maturation of extramitochondrial
CC Fe-S proteins. The NUBP1-NUBP2 heterotetramer forms a Fe-S scaffold
CC complex, mediating the de novo assembly of an Fe-S cluster and its
CC transfer to target apoproteins. {ECO:0000256|HAMAP-Rule:MF_03039}.
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03039};
CC Note=Binds 4 [4Fe-4S] clusters per heterotetramer. Contains two stable
CC clusters in the N-termini of NUBP1 and two labile, bridging clusters
CC between subunits of the NUBP1-NUBP2 heterotetramer. {ECO:0000256|HAMAP-
CC Rule:MF_03039};
CC -!- SUBUNIT: Heterotetramer of 2 NUBP1 and 2 NUBP2 chains.
CC {ECO:0000256|HAMAP-Rule:MF_03039}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496,
CC ECO:0000256|HAMAP-Rule:MF_03039}.
CC -!- SIMILARITY: Belongs to the Mrp/NBP35 ATP-binding proteins family.
CC NUBP2/CFD1 subfamily. {ECO:0000256|HAMAP-Rule:MF_03039}.
