Abstract

We identified cytosine-rich regions adjacent to guanine-rich regions in protease genes. A typical GC-rich sequence derived from the gene showed structural competition between a G-quadruplex and a hairpin loop, and this competition significantly affected transcription efficiency. These results suggest an impact of neighboring sequences on the gene expression of guanine-rich sequences.

摘要

我们在蛋白酶基因中鉴定到了临近鸟嘌呤富集区的胞嘧啶富集区。来源于 基因的典型 GC 富集序列表现出 G-四链体和发夹环之间的结构竞争,这种竞争显著影响了转录效率。这些结果表明了临近序列对富含鸟嘌呤序列的基因表达的影响。
