Description

Unleash the power of our Recombinant Human ISCU protein in your signal transduction research, and explore its role in the vital process of iron-sulfur cluster biogenesis. ISCU, the Iron-sulfur cluster assembly enzyme, is a critical component in the assembly and transfer of Fe-S clusters, which serve as essential cofactors for a multitude of cellular processes, including electron transfer and enzyme catalysis.

Our Recombinant Human ISCU protein offers a full-length sequence (1-167 amino acids) for optimal functionality and bioactivity. Produced in E. coli, this protein features an N-terminal GST-tag, facilitating efficient purification and detection without affecting the protein's native structure or biological activity. With a purity of greater than 90% as determined by SDS-PAGE, our Recombinant Human ISCU protein guarantees consistent and reliable results, providing a dependable tool for your research endeavors. Choose from liquid or lyophilized powder forms to best suit your experimental needs.

Target Background

Function
Scaffold protein for the de novo synthesis of iron-sulfur (Fe-S) clusters within mitochondria, which is required for maturation of both mitochondrial and cytoplasmic Functions as a cytoplasmic scaffold protein for the de novo synthesis of iron-sulfur clusters in the cytoplasm.
Gene References into Functions
  1. identifies an important regulatory role for zinc-bound ISCU in modulation of the human Fe-S assembly system in vitro and reports no 'FXN bypass' effect on mutations at position Met140 in human ISCU PMID: 30031876
  2. we report the first heterozygous dominant mutation in ISCU; notably, this alteration resulted in a similar phenotype as the recessive ISCU disease previously described. PMID: 29079705
  3. When ISCU was replaced by the fully structured variant ISCU(M108I), the addition of rdFDX2 to the [NIA-ISCU(M108I)-FXN]2 complex led to the release of FXN. Thus, the displacement of FXN by rdFDX2 explains the failure of FXN to stimulate Fe-S cluster assembly on ISCU(M108I). PMID: 29406711
  4. We have shown that ASO treatment diminished aberrant splicing and increased ISCU protein levels in both patient fibroblasts and patient myotubes in a concentration dependent fashion. Upon ASO treatment, levels of SDHB in patient myotubular cell lines increased to levels observed in control myotubular cell lines PMID: 28007899
  5. The NFS1/ISD11 complex further interacts with scaffold protein ISCU and regulator protein frataxin, thereby forming a quaternary complex for Fe-S cluster formation. PMID: 28271877
  6. Molecular dynamics flexible fitting of protein structures docked into the EM map of the model revealed a [FXN(42-210)]24.[NFS1]24.[ISD11]24.[ISCU]24 complex, consistent with the measured 1:1:1:1 stoichiometry of its four components. PMID: 27519411
  7. ISCU expression was decreased in the majority of human liver cancer tissues, and its reduced expression was significantly associated with p53 mutation. PMID: 26560363
  8. Thus, driven by acquired (hypoxia) or genetic causes, the miR-210-ISCU1/2 regulatory axis is a pathogenic lynchpin causing iron-sulfur deficiency and pulmonary hypertension. PMID: 25825391
  9. The core Fe-S biosynthetic enzymatic complex generated [2Fe-2S] cluster intermediates that converted to stable [2Fe-2S] clusters bound to uncomplexed ISCU2. PMID: 26016389
  10. IscU is a new substrate of MK2 both in Drosophila cells and in human cells PMID: 25204651
  11. Fe-S assembly protein (ISCU2) and frataxin convert substrates l-cysteine, ferrous iron, and electrons into Fe-S clusters. PMID: 24971490
  12. the G50E iron-sulfur cluster scaffold protein (ISCU) mutation has a role in mitochondrial myopathy PMID: 24573684
  13. NFS1 binds preferentially to the D-state of ISCU while mtHSP70 binds preferentially to the D-state of ISCU and HSC20 binds preferentially to the S-state of ISCU. PMID: 23940031
  14. mTORC1 associates with ISCU and phosphorylates ISCU at serine 14. This phosphorylation stabilized ISCU protein. PMID: 23508953
  15. MicroRNA-210 correlates negatively with its gene target ISCU at the protein and mRNA level. MicroRNA-210 correlated with positive outcome variables PMID: 23449350
  16. ISCU protein deficiency in patients results from muscle-specific mis-splicing and oxidative stress. PMID: 23035118
  17. this study unveiled a signaling axis of HIF-1alpha/miRNA-210/iron-sulfur cluster scaffold protein in a subset of head and neck paragangliomas that could have an impact on SDHB protein stability by a mechanism independent of succinate dehydrogenase mutations PMID: 22977270
  18. Photoreactive heterotrifunctional chemical cross-linking confirmed the interaction between frataxin and ISCU in the presence of iron and validated that transient interactions can be covalently trapped with this method. PMID: 22897349
  19. iron-sulfur cluster scaffold homologue down-regulation by miR-210 perturbing trophoblast iron metabolism is associated with defective placentation PMID: 21801864
  20. Exchange of [2Fe-2S] centers between glutaredoxin 2 and the cluster scaffold protein ISU, supports a direct link for glutaredoxin 2 and glutathione involvement in ISU promoted Fe-S cluster biosynthesis. PMID: 21437321
  21. Data show that the highest level of incorrectly spliced ISCU mRNA was found in skeletal muscle. PMID: 21165651
  22. miR-210 mediates a new mechanism of adaptation to hypoxia, by regulating mitochondrial function via iron-sulfur cluster metabolism and free radical generation PMID: 20436681
  23. ISCU and COX10 are target genes of miR-210 related to mitochondrial metabolism PMID: 20498629
