Riboswitches are RNA structures traditionally viewed as acting in cis to regulate downstream gene expression in bacteria. In a recent issue of Cell, Loh and colleagues report on the ability of a riboswitch to act in trans to modulate the expression of a critical bacterial virulence regulator.
Riboswitches 是传统上被视为在顺式作用以调节细菌下游基因表达的 RNA 结构。在最近一期的《Cell》杂志上,Loh 及其同事报道了一个 riboswitch 能够在反式作用中调节关键细菌毒力调节因子的表达的能力。
