脊椎动物 RNA聚合酶I 的启动子有两部分组成,包括转录起点附近的核心启动子 (core promoter) ,和起点 5'上游 100bp 左右的上游控制元件 (upstream control element,UCE) 。核心启动子从 -45 到 +20,负责转 录的起始。 UCE 从-180 延伸到 -107,此区可增加核心元件的转录起始的效率。 RNA Pol I需要2种辅助...

前rRNA基因转录起始点上游有两个顺式作用元件(cis acting element),一个是跨越起始点的核心元件(core element),另一个在–100bp处有上游调控元件(upstream control element,UCE)。RNA聚合酶I催化的转录需要2种转录因子,分别称为上游结合因子(upstream binding factor,UBF)和选择性因子1(selective factor1,SL1)。SL1...
