Protein
Cytosolic Fe-S cluster assembly factor NBP35
Organism
Kluyveromyces lactis (strain ATCC 8585 / CBS 2359 / DSM 70799 / NBRC 1267 / NRRL Y-1140 / WM37)
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.
Similarity
Belongs to the Mrp/NBP35 ATP-binding proteins family. NUBP1/NBP35 subfamily.
