  • 产品描述：

    A target DNA sequence encoding to the 700-1216aa of human probable global transcription activator SNF2L2 (SMARCA2) was fused with an N-terminal 6xHis-SUMO-tag and then expressed in E.coli. The resulting protein is the partial-length recombinant SMARCA2 protein. Its purity is over 90% measured by SDS-PAGE. This SMARCA2 protein migrated to a 90 kDa molecular mass band on the gel. The in-stock protein allows it to reach your lab bench faster. This recombinant SMARCA2 protein may be applied to generate specific antibodies and in the studies of neuroscience.

    SMARCA2 is frequently downregulated in tumors. Tumors with high SMARCA2 levels are mostly associated with a good prognosis. The expression of SMARCA2 is negatively regulated by mitogenic stimulation and Ras and ERK signaling, and restoration of SMARCA2 concentration results in reversion of the transformed phenotype. Studies show that SMARCA2 is required for cell cycle arrest during myoblast differentiation.

靶点详情

  • 功能：
    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. Belongs to the neural progenitors-specific chromatin remodeling complex (npBAF complex) and the neuron-specific chromatin remodeling complex (nBAF complex). During neural development a switch from a stem/progenitor to a postmitotic chromatin remodeling mechanism occurs as neurons exit the cell cycle and become committed to their adult state. The transition from proliferating neural stem/progenitor cells to postmitotic neurons requires a switch in subunit composition of the npBAF and nBAF complexes. As neural progenitors exit mitosis and differentiate into neurons, npBAF complexes which contain ACTL6A/BAF53A and PHF10/BAF45A, are exchanged for homologous alternative ACTL6B/BAF53B and DPF1/BAF45B or DPF3/BAF45C subunits in neuron-specific complexes (nBAF). The npBAF complex is essential for the self-renewal/proliferative capacity of the multipotent neural stem cells. The nBAF complex along with CREST plays a role regulating the activity of genes essential for dendrite growth.

    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. Specific patterns of gene mutations including CTNNB1, TERT, ARID1A and SMARCA2 exist in alcohol-related HCC. [review] PMID: 28296015

    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
