Note: The complete sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
If the exact amino acid sequence of this recombinant protein is critical to your application, please explicitly request the full and complete sequence of this protein before ordering.
蛋白標簽：

C-terminal 6xHis-tagged
產品提供形式：

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.
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：

3-7 business days
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 the telomerase ribonucleoprotein (RNP) complex that is essential for the replication of chromosome termini. May have a general role in telomere regulation. Promotes in vitro the ability of TERT to elongate telomeres. Overexpression induces telomere uncapping, chromosomal end-to-end fusions (telomeric DNA persists at the fusion points) and did not perturb TRF2 telomeric localization. Binds to the single-stranded 5'-(GTGTGG)(4)GTGT-3' telomeric DNA, but not to a telomerase RNA template component (TER).; Plays a role in nonsense-mediated mRNA decay. Is thought to provide a link to the mRNA degradation machinery as it has endonuclease activity required to initiate NMD, and to serve as an adapter for UPF1 to protein phosphatase 2A (PP2A), thereby triggering UPF1 dephosphorylation. Degrades single-stranded RNA (ssRNA), but not ssDNA or dsRNA.
基因功能參考文獻：
1. Nonsense-mediated mRNA decay (NMD) substrates with PTCs undergo constitutive SMG6-dependent endocleavage, rather than SMG7-dependent exonucleolytic decay. In contrast, the turnover of NMD substrates containing upstream ORFs and long 3' UTRs involves both SMG6- and SMG7-dependent endo- and exonucleolytic decay, respectively; extent to which SMG6 and SMG7 degrade NMD substrates is determined by the mRNA architecture. PMID: 28461625
2. Transcriptome-wide identification of nonsense-mediated mRNA decay-targeted human mRNAs reveals extensive redundancy between SMG6- and SMG7-mediated degradation pathways. PMID: 27864472
3. A preferred sequence motif spanning most SMG6 cleavage sites has been discovered by analysis of endogenous non-sense-mediated mRNA decay targets. PMID: 25429978
4. SMG6 requires UPF1 and SMG1 for nonsense-mediated mRNA decay. PMID: 25053839
5. The study demonstrates that SMG5-SMG7 and SMG6 exhibit different and non-overlapping modes of UPF1 recognition, thus pointing at distinguished roles in integrating the complex nonsense-mediated mRNA decay interaction network. PMID: 25013172
6. Consistent with involvement of SMG6 in the decay process full-length nonsense-containing beta-globin mRNA was increased and the Delta169 decay intermediate was decreased in cells knocked down for SMG6. PMID: 24086375
7. The tricotetrapeptide repeat-containing domain within Est1A was sufficient for interaction with hTERT. PMID: 22011238
8. Data show that SMG6 interacts directly with the EJC via two conserved EJC-binding motifs (EBMs). PMID: 20930030
9. associated with most or all active telomerase in HeLa cell extracts; overexpression of hEST1A induces anaphase bridges due to chromosome-end fusions, and telomeric DNA persists at the fusion points PMID: 12676087
10. Human EST1A is associated with most or all active telomerase and is involved either directly or indirectly in telomere elongation and telomere capping. PMID: 16820686
11. Structural properties of the PIN domain indicate its putative active center consisting of invariant acidic amino acid residues, which is similar to the active center of 5' nucleases. PMID: 17557331
12. Report shows that hEST1A assembles specifically with telomerase in the context of the telomerase RNA (hTR)-hTERT ribonucleoprotein, through the high affinity of hEST1A for hTR and specific protein-protein contacts with hTERT. PMID: 17940095
