緩沖液：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
貨期：

3-7 business days

靶點詳情

功能：

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.
基因功能參考文獻：
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
24. Data suggest that frataxin may be involved in the biosynthesis of iron-sulphur proteins such as IscU1 not only within the mitochondria, but also in the extramitochondrial compartment. PMID: 16091420
25. Functional analysis of the mitochondrial and cytosolic isoforms of the human Fe-S cluster scaffold protein, ISCU. PMID: 16517407
26. the cytosolic form of ISCS is a functional cysteine desulfurase that can collaborate with cytosolic ISCU to promote de novo iron-sulfur cluster formation PMID: 16527810
27. Intron mutation in the ISCU gene, leading to incorrectly spliced mRNA, is the cause of myopathy with lactic acidosis in this family. PMID: 18296749
28. Gene ISCU was identified as a candidate within a region of shared homozygosity among patients with myopathy with severe exercise intolerance and myoglobinuria. PMID: 18304497
