Tag Info
Tag type will be determined during the manufacturing process.
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Form
Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer before Lyophilization
Tris/PBS-based buffer, 6% Trehalose.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
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.
Lead Time
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
A cytochrome P450 monooxygenase that catalyzes the side-chain hydroxylation and cleavage of cholesterol to pregnenolone, the precursor of most steroid hormones. Catalyzes three sequential oxidation reactions of cholesterol, namely the hydroxylation at C22 followed with the hydroxylation at C20 to yield 20R,22R-hydroxycholesterol that is further cleaved between C20 and C22 to yield the C21-steroid pregnenolone and 4-methylpentanal. Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate and reducing the second into a water molecule. Two electrons are provided by NADPH via a two-protein mitochondrial transfer system comprising flavoprotein FDXR (adrenodoxin/ferredoxin reductase) and nonheme iron-sulfur protein FDX1 or FDX2 (adrenodoxin/ferredoxin).

  1. melatonin not only elevated progesterone (P) secretion, but also upregulated expressions of StAR and Cyp11a1 and also had an increased Ihh expression in endometrium. PMID: 28749439
  2. reduction in expression mirrored reduction in adrenal corticosterone output PMID: 29046340
  3. The results demonstrated that ZnT7 gene silencing downregulated the expression of StAR, P450scc and 3beta-HSD as well as progesterone concentrations in the human chorionic gonadotrophin-stimulated Leydig tumor cells. PMID: 27121848
  4. 1,25D3 modulates CD8+ T cell phenotype via recruitment of the VDR transcription factor to the promoter region of Cyp11a1 leading to prevention of lung allergic responses. PMID: 26750596
  5. Data from Cyp11a1 transgenic mice suggest that overexpression of Cyp11a1 results in reduced pregnancy rate, impaired implantation/placentation, decreased litter size, and stillbirth; overexpression of Cyp11a1 disrupts development of corpus luteum. PMID: 23966322
  6. Cyp11a1 plays an important role in the development of peanut allergy, regulating peanut-induced allergic responses through effects on steroidogenesis, an essential pathway in T(H)2 differentiation. PMID: 23870673
  7. Cyp11a1 controls the phenotypic conversion of CD8(+) T cells from IFN-gamma to IL-13 production, linking steroidogenesis in CD8(+) T cells, a nonclassical steroidogenic tissue, to a proallergic differentiation pathway PMID: 23630275
  8. Sodium fluoride inhibited expression of StAR and P450scc in mouse Leydig tumor cells, which inhibited progesterone secretion. PMID: 22443068
  9. LH/hCG tightly regulates MKP-2 expression, which modulates the induction of CYP11A1 by 8Br-cAMP. PMID: 23471219
  10. Cyp11a1 null embryos had adrenal medulla with abnormal mitochondria. Cells did not synthesized no epinephrine. Decreased diencephalon Hsd11b1, increased Crh, and increased pituitary Pomc expression, thus higher plasma ACTH PMID: 22962254
  11. Data suggest that the 5' flanking region of CYP11A gene contains sequences between 2.5 and 5 kb that are necessary for expression of mouse CYP11A in Leydig cells but not in adrenal cells. [REVIEW] PMID: 22217834
  12. Daxx, a HIPK kinase substrate in the apoptosis pathway, was phosphorylated by HIPK3 at Ser-669 in response to cAMP stimulation. PMID: 22199361
  13. Prenatal exposure to ethanol increased expressions of StAR and P450scc in maternal adrenal and decreased them in fetal adrenal. PMID: 20627497
  14. Pubertal Cd exposure markedly reduced mRNA and protein levels of testicular StAR, P450scc, P450(17alpha) and 17beta-HSD in mice. PMID: 19897027
  15. Transcription of cholesterol side-chain cleavage cytochrome P450 in the placenta: activating protein-2 assumes the role of steroidogenic factor-1 by binding to an overlapping promoter element. PMID: 12145340
  16. Cyp11a1 null mice display a lack of steroid production, abnormal gene expression, and aberrant reproductive organ development resemble various steroid deficiency syndromes. PMID: 12145347
  17. Male CYP11A1 null mice are feminized and their adrenals and genitalia accumulate excessive amounts of lipid PMID: 12530664
  18. Proximal SF-1 binding site plays important role in regulating tissue-specific expression of Cyp11a1 and stress response. PMID: 15666831
  19. This study sought to elucidate overlooked modes of regulation of P450scc transcription in the rodent placenta and ovary. PMID: 17213386
  20. SF-1 and AP-1 cooperate to activate CYP11A1 transcription in vitro and in vivo. PMID: 17218410
  21. Data show that HDAC inhibitors suppressed the expression of steroidogenic gene CYP11A1 and decreased steroid secretion by increasing the ubiquitination and degradation of SF-1, a factor important for the transcription of all steroidogenic genes. PMID: 17709382
  22. Data show that the mutation of the SF-1 response element of Cyp11a1 results in reduced stress response due to decreased adrenal CYP11A1 expression and insufficient stress-induced glucocorticoids secretion. PMID: 18174359
  23. Heterologous expression in yeast of mCYP11A1 fusions with different topogenic signals of yeast mitochondrial proteins was used to gain insight in the mechanism of its topogenesis in mitochondria. PMID: 18621100
