描述

The CDK8-CCNC-MED12 protein is an important component of the mediator complex, acting as a bridge for gene transcription regulation, transmitting information from gene-specific regulatory factors to RNA polymerase II. It is recruited to the promoter, assembles a preinitiation complex, and promotes transcription. CDK8 Protein, Human ( Unactive, sf9, GST) is the recombinant human-derived CDK8, expressed by Sf9 insect cells , with GST labeled tag. The total length of CDK8 Protein, Human ( Unactive, sf9, GST) is 464 a.a.,

研究背景

CDK8-CCNC-MED12 蛋白是介导复合体的重要组成部分,介导复合体是几乎所有 RNA 聚合酶 II 依赖性基因的基因转录调节不可或缺的共激活因子。作为介体复合体的一部分,它充当桥梁,将信息从基因特异性调节蛋白传递到基础 RNA 聚合酶 II 转录机制。该复合物通过与调节蛋白的直接相互作用被招募至启动子,作为功能性预起始复合物与 RNA 聚合酶 II 和一般转录因子组装的支架。CDK8-CCNC-MED12 通过磷酸化 RNA 聚合酶 II 大亚基的 C 端结构域 (CTD) 发挥其调节功能,可能抑制转录起始复合物的形成。此外,它磷酸化 CCNH,导致 TFIIH 复合物下调并随后抑制转录。值得注意的是,CDK8-CCNC-MED12 通过与 MAML1 相互作用而被招募,导致 NOTCH 胞内结构域过度磷酸化并促进其降解。这些多方面的作用强调了 CDK8-CCNC-MED12 在协调基因转录调控的复杂过程中的重要性。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
