以乳糖操纵子(lac operon)为例,说明什么是顺式作用元件(cis-acting element),什么是反式作用因子(trans-acting factor)?它们各自如何发挥作用?答:顺式作用元件是指DNA分子上对基因表达有调节活性的某些特定的调控序列,其活性仅影响与其自身处于同一DNA分子上的基因,这种DNA序列多位于基因旁侧或内含子中,不编码蛋白质...

在基因组中,与Cis-作用调控元件相对应的是转录因子结合位点(Trans-Acting Regulatory Element)。Cis-作用调控元件位于基因的上游或下游区域,并且可以在基因的调控区域内。其所在的位置在整个基因组内可能是特异性或普遍性的,它们对于控制基因的启动、沉默、重编程和调控等过程起着重要作用。 Cis-作用调控元件的分析方法...

These effects are measurably rescued by ectopic expression of mouse or human Firre/FIRRE transgenes, supporting conserved trans-acting roles. We also find that the compact 3D structure of the Xi partly depends on the Firre locus and its RNA. In common lymphoid progenitors and T-cells Firre ...
Gene transfer experiments using estrogen-responsive cells have shown that the 13 bp perfect palindromic element GGTCACTGTGACC found upstream of the Xenopus laevis vitellogenin gene A2 promoter mediates hormonal stimulation and thus, was called the estrogen-responsive element (ERE). In the Xenopus ...
