    在真核细胞中,转录部分受高分子量共激活复合物的调节,这些复合物在转录激活剂和RNA聚合酶之间传递信号。RNA聚合酶II(RNAPII)全酶包含许多蛋白质,这些蛋白质主要由RNA加工因子、RNA解旋酶、通用转录因子和SRB共激活复合物组成。RNAPII介导的基础和基因特异性转录激活需要各种辅因子的结合,包括PC4(人类正辅因子4)。正辅因子4与转录因子IIA(TFIIA)的激活域和TATA结合蛋白(TBP)相关因子(TAFs)相互作用,直接结合双链DNA。正辅因子4根据这些转录因子和全酶成分的存在与否,诱导RNAPII基础转录的激活和抑制。此外,正辅因子4被TFIID和TFIIH磷酸化,从DNA启动子区域释放正辅因子4,从而抑制正辅因子4组装成转录促进复合物并阻断转录。

    When should the TransCruz reagent sc-166279 X be used instead of the standard form sc-166279?

    Asked by: Cweed
    Thank you for your question. We recommend using the TransCruz reagent form when performing ChIP or GelShift assays. This form can also be used in other applications such as Western Blot or IHC, but the dilution should be adjusted by a factor of 10 to account for the higher original concentration.
