Q&A and Customer Reviews


I am interested in the SMARCA2 Recombinant Protein (CSB-EP021799HU), but have a few questions first:
1.What is the SUMO tag’s length in CSB-EP021799HU?
2.For product, can these tags be cleaved?
3.The MW of SMARCA2 is ~180 kDa. Why is this protein (CSB-EP021799HU) only 76 kDa?

Thanks for your inquiry.
Generally the MW of SUMO-tag on gel is relative larger than the theoretical size. The theoretical size is about 4 kDa. The MW we generally provide is 16 kDa. The tag sequence is as below.


We haven't tried to remove the tag from this protein before, so we can't guarantee 100% success.If we fail in removing the tag, we won’t charge for any extra cost.
The full-length protein is 1590aa and the MW is ~180 kDa. The above protein we provide is a fragment with 700-1216aa expression region and the MW is ~59.7 kDa. The target protein sequence is as below.


So the MW of the fusion protein is 75.7 kDa (16+59.7=75.7).

I have aquestion about item CSB-EP021799HU Recombinant human Probable global transcription activator SNF2L2:
Regarding the purification procedures for this protein – is the protein entirely soluble when expressed in the host cell or are denaturation / renaturation protocols used to prepare this protein?
Would you have this information available that you could share?

So nice to receive your inquiry. The product details are confirmed as below.

Target Data

Function Involved in transcriptional activation and repression of select genes by chromatin remodeling (alteration of DNA-nucleosome topology). Component of SWI/SNF chromatin remodeling complexes that carry out key enzymatic activities, changing chromatin structure by altering DNA-histone contacts within a nucleosome in an ATP-dependent manner. Binds DNA non-specifically
Gene References into Functions

  2. High expression of SMARCA2 is associated with benign differentiated tumors. PMID: 29391527
  3. Here, the authors show that C-terminally truncated forms of both SMARCA2 and SMARCA4, produced by caspase-mediated cleavage, accumulate in cells infected with different RNA or DNA viruses. The levels of truncated SMARCA2 or SMARCA4 strongly correlate with the degree of cell damage and death observed after virus infection. PMID: 29848589
  4. at genes where BRG1 and BRM antagonize one another we observe a nearly complete rescue of gene expression changes in the combined BRG/BRM double knockdown PMID: 29273066
  5. Expression of BRM and MMP2 in the thoracic aortic aneurysm and aortic dissection is very high, indicating that BRM and MMP2 may play important roles in the occurrence and development of thoracic aortic aneurysm and aortic dissection. PMID: 28678310
  6. Although Genome-Wide Association studies have not been carried out in the field of alcohol-related hepatocellular carcinoma (HCC), common single nucleotide polymorphisms conferring a small increase in the risk of liver cancer risk have been identified.

  9. Epigenetic regulatory molecules bind to two BRM promoter sequence variants but not to their wild-type sequences. These variants are associated with adverse overall and progression-free survival. Decreased BRM gene expression, seen with these variants, is also associated with worse overall survival PMID: 27827316
  10. We also demonstrate that tazemetostat, a potent and selective EZH2 inhibitor currently in phase II clinical trials, induces potent antiproliferative and antitumor effects in SCCOHT cell lines and xenografts deficient in both SMARCA2 and SMARCA4. These results exemplify an additional class of rhabdoid-like tumors that are dependent on EZH2 activity for survival. PMID: 28292935

  13. We conclude that their features better resemble Coffin-Siris syndrome, rather than Nicolaides-Baraitser syndrome and that these features likely arise from SMARCA2 over-dosage.

Copy number analysis in patients with features that overlap with Coffin-Siris syndrome is recommended to further determine their genetic aspects. PMID: 27264538
  14. BRM could activate JAK2/STAT3 pathway to promote pancreatic cancer growth and chemoresistance. PMID: 28602977
