Target Details

Target Function Probable component of the SCF (SKP1-CUL1-F-box protein) E3 ubiquitin ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins involved in cell cycle progression, signal transduction and transcription. CRLs complexes and ARIH1 collaborate in tandem to mediate ubiquitination of target proteins, ARIH1 mediating addition of the first ubiquitin on CRLs targets. Through the RING-type zinc finger, seems to recruit the E2 ubiquitination enzyme to the complex and brings it into close proximity to the substrate. Promotes the neddylation of CUL5 via its interaction with UBE2F. May play a role in protecting cells from apoptosis induced by redox agents.
Subcellular Location Cytoplasm. Nucleus.
Protein Families RING-box family

Tissue Specificity Expressed in heart, liver, skeletal muscle and pancreas. At very low levels expressed in brain, placenta and lung.

Gene Functions References

  1. We demonstrated that RNF7 knockdown induced growth suppression of prostate cancer cells and inactivated ERK1/2 pathway, which suggested RNF7 might be a potential novel therapeutic target for CRPC. PMID: 28252001
  2. Results identified RNF7 to interact with CARMA2 regulating its NF-kappaB-activating capacity. Mechanistically, RNF7 influences CARMA2 signaling by regulating the ubiquitination state of MALT1 and the NF-kappaB-regulatory molecule NEMO. PMID: 29194363
  3. Sag is a Kras-cooperating oncogene that promotes lung tumorigenesis PMID: 24430184
  4. NEDD4-1 overexpression sensitizes cancer cells to etoposide-induced apoptosis by reducing SAG levels through targeted degradation. SAG is added to a growing list of NEDD4-1 substrates and mediates its biological function. PMID: 25216516
  5. RNF7 gene variant is associated with the risk of developing liver fibrosis and cirrhosis in an Eastern European population. PMID: 28338112
  6. MAF1, RNF7 and SETD3 are identified as PCNA-associated proteins in human cells and given this interaction with PCNA, Maf1, RNF7, and SetD3 are potentially involved in DNA replication, DNA repair, or associated processes. PMID: 26030842
  7. These findings indicate that Rbx1 and Rbx2 can both activate Cul5-Vif E3 ligase in vitro, but they may undergo a more delicate selection mechanism in vivo. PMID: 25912140
  8. Single nucleotide polymorphism rs16851720 was associated with liver fibrosis progression. PMID: 22841784
  9. Data suggest that the sensitive-to-apoptosis gene may be a candidate gene for good prognosis in rectal cancer, independent of therapeutic response of different individuals. PMID: 22171132
  10. SAG plays an important role in regulating ionizing radiation-induced apoptosis PMID: 20933570
  11. The findings showed that SAG E3 ubiquitin ligase plays an essential role in cancer cell proliferation and tumor growth PMID: 20103673
  12. SAG possesses a potent peroxidase property to decompose hydrogen peroxide in the presence of dithiothreitol PMID: 11999705
  13. results show that the Ring-H2 finger motif of CKBBP1 is necessary for efficient binding to CKIIbeta, as well as for optimal cell proliferation PMID: 12470599
  14. sensitive to apoptosis gene protein inhibits peroxynitrite-induced DNA damage. PMID: 12565832
  15. results indicate that protein kinase CKII may control IkappaBalpha and p27Kip1 degradation and thereby G1/S phase transition through the phosphorylation of threonine 10 within CKBBP1 protein PMID: 12748192
  16. These studies suggested that CK2 might regulate SAG-SCF E3 ligase activity through modulating SAG's stability, rather than its enzymatic activity directly. PMID: 16874460
  17. Endogenous levels of pro-caspase 3 were decreased by overexpression of SAG protein. PMID: 17217622
  18. Promotes hypoxia-inducible factor 1 alpha subunit (HIF-1 alpha) ubiquitination and degradation. PMID: 17828303
  19. Sensitive to apoptosis gene may play an important role in regulating the apoptosis induced by heat shock presumably through maintaining the cellular redox status. PMID: 18454945

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
