冠状病毒IBV的基因组RNA在两个重叠的开放阅读框的连接处含有有效的核糖体移码信号。我们已经通过缺失分析定义了包含重叠区域的86个核苷酸的序列,该重叠区域足以允许在异源背景下的移码。信号的上游边界由序列UUUAAAC组成,这是核糖体滑动的可能位点。我们通过创建互补核苷酸的变化,这种“滑”序列的RNA下游折叠成一个三级结构,称为假结,其形成是必要的有效移码。
The genomic RNA of the coronavirus IBV contains an efficient ribosomal frameshifting signal at the junction of two overlapping open reading frames. We have defined by deletion analysis an 86 nucleotide sequence encompassing the overlap region which is sufficient to allow frameshifting in a heterologous context. The upstream boundary of the signal consists of the sequence UUUAAAC, which is the likely site of ribosomal slippage. We show by creation of complementary nucleotide changes that the RNA downstream of this “slippery” sequence folds into a tertiary structure termed a pseudoknot, the formation of which is essential for efficient frameshifting.
