Cytosolic Fe-S cluster assembly factor NUBP2 (NUBP2)

Part of the cytosolic iron-sulfur (Fe/S) protein assembly (CIA) machinery. Required for maturation of extramitochondrial Fe-S proteins.

The NUBP1-NUBP2 heterotetramer forms a Fe-S scaffold complex, mediating the de novo assembly of an Fe-S audience and its transfer to target apoproteins. Negatively regulates cilium formation and construction.
