Form Liquid or 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 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, pH 8.0.
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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Storage Condition Store at -20°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.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Data

Function Induces CD27-mediated apoptosis. Inhibits BCL2L1 isoform Bcl-x(L) anti-apoptotic activity. Inhibits activation of NF-kappa-B and promotes T-cell receptor-mediated apoptosis.
Gene References into Functions
  1. Loss of SIVA1 expression is associated with nasopharyngeal carcinoma. PMID: 26406409
  2. These findings collectively reveal a novel role for the p53 target gene SIVA both in regulating metabolism and in enabling tumorigenesis, independently of p53. PMID: 25813352
  3. Functional test demonstrated that Siva1 significantly inhibited the invasion and migration of HCT116 cells. PMID: 25374190
  4. electrical stimulation -inducible SIVA1 modulates p53 activities in proliferating keratinocytes, and exogenous electrical stimulation affects p53/HDM2/SIVA1 axis leading to increased proliferation during re-epithelialization PMID: 25431847
  5. SIVA1 interacts with RAD18 and serves as a molecular bridge between RAD18 and PCNA, thus targeting the E3 ligase activity of RAD18 onto PCNA. PMID: 24958773
  6. Siva1 promotes the ubiquitination and degradation of ARF, which in turn affects the stability of p53. PMID: 23462994
  7. Upon stimulation of thromboxane A2, degradation of Siva1 is impeded, resulting in an accumulation of the protein, which translocates from the nucleus to the cytosol. PMID: 22343716
  8. negative regulator of IL-2 gene expression in Treg cells PMID: 21955384
  9. Data show that low levels of Siva1 and Ser16-phosphorylated stathmin correlate with high metastatic states of breast cancer cells. PMID: 21768358
  10. These findings suggest that the caspase-dependent pathway for induction of apoptosis is involved in Siva-1-mediated influenza A virus replication. PMID: 21048035
  11. These results suggest that Siva-mediated unprovoked apoptosis is not likely to be involved in the pathogenesis of Familial Mediterranean fever. PMID: 20934406
  12. Siva-1 forms a functional complex with Tyk2 and participates in the transduction of signals that inhibit B lymphocyte growth. PMID: 20727854
  13. Siva-1 putative amphipathic helical region (SAH) binds BCL-XL and sensitizes cells to UV radiation induced apoptosis PMID: 14739602
  14. Overexpression of Siva-1 in T lymphocytes triggers the activation of a caspase-dependent death pathway including a pivotal mitochondrial step. Both N- and C-terminal domains of Siva proteins display the ability to induce a cell death process in T cells. PMID: 15034012
  15. Siva-1 has a role, through its inhibitory effect on NF-kappaB activity, in TCR-mediated AICD with implications in peripheral tolerance, T-cell homeostasis and cancer PMID: 16491128
  16. determined the N-terminal part of Siva as the binding region for CD27; the peroxisomal membrane protein PMP22 is a new interaction partner of Siva and may be involved in the host response against CVB3. PMID: 16683188
  17. Confirming the anti-apoptotic role of HPV-16 E7 in the HaCaT cellular model, evaluated by nuclear morphology, it was also found that Siva-1 expression produced a significant increase of the apoptotic rate in UV radiation-exposed HaCaT cells. PMID: 17348035
  18. Results suggest that Siva-1 might participate in the CD4-initiated signaling apoptotic pathway induced by the HIV-1 envelope in T-lymphoid cells. PMID: 17653867
  19. lysophosphatidic acid 2 receptor mediates down-regulation of Siva-1 to promote cell survival PMID: 17965021
  20. Data show that Siva and pyrin are co-expressed, and that pyrin modulates the apoptotic response to oxidative stress mediated by Siva. PMID: 18330885
  21. Telethonin might be involved in CVB3-mediated cell damage and in the resulting cardiac dysfunction due to the interaction with Siva. PMID: 18849585
  22. Siva-1 has a role in negatively regulating NF-kappaB activation by targeting TRAF2. PMID: 19392652
  23. Siva1 is an important mediator for the Hdm2-p53 interaction and is an integral component of the negative feedback mechanism for p53 inhibition. PMID: 19590512
