產品提供形式：

Liquid or Lyophilized powder Warning: in_array() expects parameter 2 to be array, null given in /www/web/cusabio_cn/public_html/caches/caches_template/default/content/show_product_protein.php on line 662
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.
緩沖液：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
復溶：

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.
儲存條件：

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

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：

Basically, we can dispatch the products out in 3-7 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

靶點詳情

功能：

Component of SEC61 channel-forming translocon complex that mediates transport of signal peptide-containing precursor polypeptides across the endoplasmic reticulum (ER). Forms a ribosome receptor and a gated pore in the ER membrane, both functions required for cotranslational translocation of nascent polypeptides. May cooperate with auxiliary protein SEC62, SEC63 and HSPA5/BiP to enable post-translational transport of small presecretory proteins. Component of a ribosome-associated ER translocon complex involved in multi-pass membrane protein transport into the ER membrane and biogenesis. The SEC61 channel cooperates with the translocating protein TRAM1 to import nascent proteins into the ER. Controls the passive efflux of calcium ions from the ER lumen to the cytosol through SEC61 channel, contributing to the maintenance of cellular calcium homeostasis. Plays a critical role in nephrogenesis, specifically at pronephros stage.

1. Shows that inhibition of Sec61 by mycolactone drives rapid and broad translational reprogramming of a subset of genes involved in stress responses that is initially protective but ultimately leads to cell death PMID: 29540678
2. Unpicking the central dogma of molecular biology step-by-step identifies the Sec61 translocon as the target of anti-inflammatory activity of mycolactone, explaining why production of Sec61-dependent proteins (secretory, ER resident and membrane bound) is lost even though transcription and translation are unaffected. PMID: 24699819
3. The direct contribution of Sec61 to antigen cross-presentation, endosome-to-cytosol export, and endoplasmic reticulum-to-cytosol export. PMID: 28679634
4. The authors propose that the Sec61-IRE1alpha complex defines the extent of IRE1alpha activity and may determine cell fate decisions during endoplasmic reticulum stress conditions. PMID: 28504640
5. EPO (7q22) and SEC-61(7p11) emerged as new candidate genes susceptible to genetic losses with 57.7% deletions identified in regions on chromosome 7. PMID: 27282568
6. Tomography densities at subnanometer resolution revealed an intricate network of interactions between the ribosome, Sec61 and accessory translocon components that assist in protein transport, membrane insertion and maturation PMID: 27373685
7. The discovery of export-specific sec61 mutants and of mammalian ER-associated degradation (ERAD) substrates whose export is dependent on the 19S regulatory particle suggest that dismissal of a role of Sec61 in export may have been premature. PMID: 27932072
8. the effect of mycolactone on transmembrane protein biogenesis depends on how the nascent chain initially engages the Sec61 complex. PMID: 28219954
9. data provide definitive genetic evidence that Sec61 is the host receptor mediating the diverse immunomodulatory effects of mycolactone and identify Sec61 as a novel regulator of immune cell functions. PMID: 27821549
10. findings provide a mechanism by which mutations in SEC61A1 lead to an autosomal-dominant syndromic form of progressive chronic kidney disease; we highlight protein translocation defects across the endoplasmic reticulum membrane, the principal role of the SEC61 complex, as a contributory pathogenic mechanism for autosomal-dominant tubulo-interstitial kidney disease PMID: 27392076
11. BiP facilitates Sec61 channel closure (i.e. limits ER Ca(2+) leakage) via the Sec61 channel with the help of ERj3 and ERj6 PMID: 26085089
12. Sec61 complex is calcium permeable, the Sec61 complex is tightly regulated in its equilibrium between the closed and open conformations, or "gated", by ligands, such as signal peptides of the transport substrates PMID: 24934166
13. Short secretory proteins appear to be ubiquitously transported across the ER membrane through the Sec61 translocon. PMID: 22505607
14. The human SEC61A1 gene is essential for cell growth and viability. PMID: 22375059
15. BiP limits ER Ca(2+) leakage through the Sec61 complex by binding to the ER lumenal loop 7 of Sec61alpha in the vicinity of tyrosine 344. PMID: 22796945
16. The present study indicates that Sec61alpha is a host protein involved in Ebola virus (EBOV) replication, specifically in EBOV genome transcription and replication. PMID: 21987770
17. Silencing the SEC61A1 gene using two different siRNAs in HeLa cells for 96 hours had little effect on cell growth and viability. However, calcium leakage from the ER was greatly decreased in the SEC61A1-silenced cells. PMID: 21406962
18. At the cellular level, two different calmodulin antagonists stimulated calcium release from the endoplasmic reticulum through SEC61 channels. PMID: 21102557
