| case <OC:Saccharomycetes> | |
| FUNCTION | Component of the cytosolic iron-sulfur (Fe/S) protein assembly (CIA) machinery. Required for maturation of extramitochondrial Fe-S proteins. The NBP35-CFD1 heterotetramer forms a Fe-S scaffold complex, mediating the de novo assembly of an Fe-S cluster and its transfer to target apoproteins. Required for biogenesis and export of both ribosomal subunits, which may reflect a role in assembly of the Fe/S clusters in RLI1, a protein which performs rRNA processing and ribosome export. |
| else case <OC:Fungi> | |
| FUNCTION | Component of the cytosolic iron-sulfur (Fe/S) protein assembly (CIA) machinery. Required for maturation of extramitochondrial Fe-S proteins. The @gn(NBP35)-@gn(CFD1) heterotetramer forms a Fe-S scaffold complex, mediating the de novo assembly of an Fe-S cluster and its transfer to target apoproteins. |
| else case <OC:Viridiplantae> | |
| FUNCTION | Component of the cytosolic iron-sulfur (Fe-S) protein assembly (CIA) machinery. Required for maturation of extramitochondrial Fe-S proteins. Functions as Fe-S scaffold, mediating the de novo assembly of an Fe-S cluster and its transfer to target apoproteins. Essential for embryo development. |
| else case <OC:Mammalia> | |
| FUNCTION | Component of the cytosolic iron-sulfur (Fe/S) protein assembly (CIA) machinery. Required for maturation of extramitochondrial Fe-S proteins. The @gn(NUBP1)-@gn(NUBP2) heterotetramer forms a Fe-S scaffold complex, mediating the de novo assembly of an Fe-S cluster and its transfer to target apoproteins. Implicated in the regulation of centrosome duplication. |

| COFACTOR | Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Note=Binds 3 [4Fe-4S] clusters per homodimer. Contains two stable clusters in the N-termini and one labile, bridging cluster between subunits of the homodimer.; |
| else case <OC:Fungi> | |
| COFACTOR | Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Note=Binds 4 [4Fe-4S] clusters per heterotetramer. Contains two stable clusters in the N-termini of @gn(NBP35) and two labile, bridging clusters between subunits of the @gn(NBP35)-@gn(CFD1) heterotetramer.; |

| case <OC:Viridiplantae> | |
| SUBUNIT | Homodimer and homotetramer. Predominantly homodimeric. |
| else case <OC:Mammalia> | |
| SUBUNIT | Heterotetramer of 2 NUBP1 and 2 NUBP2 chains. Interacts with KIFC1. |
| else case <OC:Fungi> | |
| SUBUNIT | Heterotetramer of 2 @gn(NBP35) and 2 @gn(CFD1) chains. |
| else | |
| SUBUNIT | Heterotetramer of 2 @gn(NUBP1) and 2 @gn(NUBP2) chains. |

| SUBCELLULAR LOCATION | Cytoplasm. Nucleus. |
| else | |
| SUBCELLULAR LOCATION | Cytoplasm. |
| end case | |
| SIMILARITY | Belongs to the Mrp/NBP35 ATP-binding proteins family. NUBP1/NBP35 subfamily. |
| case <OC:Viridiplantae> | |
| MISCELLANEOUS | Although plant and algal NBP35 proteins lack the characteristic CXXC motif in the C-terminus, thought to be required for Fe-S cluster binding, they can bind a [4Fe-4S] cluster in the C- terminus. Also, in this linage, no CFD1 partner protein homolog as found in other eukaryotes can be found. |
