介体复合物与RNA聚合酶II广泛相互作用,并调节其表达蛋白质编码基因的能力。介体调控基因表达的机制仍然知之甚少,部分原因是介体结构甚至其组成可以根据启动子环境而改变。结合人类介体复合物的庞大规模(26个亚基,1.2 MDa),这种结构适应性赋予复合物内似乎无限的调节潜力。最近的努力,以了解调解人的结构和功能已经确定了扩大的作用,包括控制前和后启动事件,它也很明显,调解人执行一般和基因特异性的作用,以调节基因表达。
The Mediator complex interacts extensively with the RNA polymerase II enzyme and regulates its ability to express protein-coding genes. The mechanisms by which Mediator regulates gene expression remain poorly understood, in part because Mediator structure and even its composition can change, depending upon the promoter context. Combined with the sheer size of the human Mediator complex (26 subunits, 1.2 MDa), this structural adaptability bestows seemingly unlimited regulatory potential within the complex. Recent efforts to understand Mediator structure and function have identified expanded roles that include control of both pre- and post-initiation events; it is also evident that Mediator performs both general and gene-specific roles to regulate gene expression.
