以乳糖操纵子(lacoperon)为例,说明什么是顺式作用元件(cis-actingelement),什么是反式作用因子(trans-actingfactor)?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。真...
Cis- and trans-acting elements involved in the regulation of the erythroid promoter of the human porphobilinogen deaminase gene Two cis-acting sequences, recognized by two erythroid-specific trans-acting factors, are involved in the regulation of the erythroid promoter of the human ... V Mignott...
In summary, transcriptional inhibition of the GnRH gene by hCG is mediated by a 95-kDa trans- acting protein, which binds to AT-rich cis-acting elements in the −91- to −81-bp region of the 5′-flanking sequence of the GnRH gene.REFERENCES...
This trans-acting effect involves SUZ12, reflecting interactions between Firre RNA and components of the Polycomb repressive complexes. Without Firre RNA, H3K27me3 decreases on the Xi and the Xi-perinucleolar location is disrupted, possibly due to decreased CTCF binding on the Xi. We also ...
In addition, mammalian trans-acting factors that bind to these promoter elements were shown to have counterparts with conserved DNA-binding activity in S. pombe. These results further illustrate the conservation of the mechanism of transcription between mammalian cells and fission yeast. 展开 ...
