Nucleotide-binding protein 2 (NBP 2) also known as cytosolic Fe-S cluster assembly factor NUBP2 is a protein that in humans is encoded by the NUBP2 gene.[1]

NUBP2 is a member of the NUBP/MRP gene subfamily of ATP-binding proteins.[2] There are two types in eukaryotes NUBP1 and NUBP2, and one novel human gene that define NBP nucleotide-binding proteins (NUBP/MRP-multidrug resistance-associated protein)[1] in mammalian cells requires the maturation of cytosolic[3] iron-sulfur (Fe/S)[4] proteins as Nubp1 is involved in the formation of extramitochondrial Fe/S proteins[2] the cell division inhibitor MinD is homologous[5] and involve two proteins components of the (FeS) protein assembly machinery closely similar cytosolic[2] soluble[4] P loop[5] NTPase where Nar1[6][7] is required for assembly,[8] identified Cfd1p[9][10] in cytosolic and nuclear Fe/S protein biogenesis[4] in yeast.[11] Nubp proteins NTPase Nbp35p.[7][8] MinD is homologous to members in MinD of E. coli, a relative of the ParA family.[5][12][13]

Morphology

Further information: Morphology

NBP35 bacterial plasmids F (the classical Escherichia coli sex factor)[5] is found in all nuclear genes in vegetative and gametic flagella of the unicellular green algae C. reinhardtii and nuclear Fe/S protein biogenesis required for cytosolic iron-sulfur protein assembly; MNP =MRP-like; MRP (Multiple Resistance and pH adaptation) MRP/NBP35-like P-loop NTPase similar to; and functions as minD_arch; cell division ATPase MinD, archaeal and homologue's of NUBP1. The NBP35 gene is conserved in archaea[14] Bacteria, Metazoa, Fungi and other Eukaryotes and with considerable divergence from the yeast; Cfd1-Nbp35 Fe-S to man. In a scaffold complex[15] protein to form large molecular assemblies that store Fe(III) and 4Fe-4S seen as secondary to defects inactivated to accomplish its functions as physiologically relevant form(s) Fe/S proteins Iron regulatory protein 1 (IRP1) is regulated through[10] prevents deficiencies and increased mutation rates[13] that characterized a plant P loop NTPase with sequence similarity to Nbp35 homologue's of NUBP1.[16]
