Gene regulation by PIWI–piRNA complexes is determined by the selection of cognate target RNAs by PIWI–piRNA. What are the mechanisms for this selection? There is a rigorous multistep control in identifying target RNAs by PIWI–piRNA structures, and RNA helicases play a potentially crucial role in this process.

PIWI蛋白进行RNA选择

PIWI-piRNA复合物对基因的调控取决于PIWI-piRNA对同源靶RNA的选择。选择的机制是什么？通过PIWI–piRNA结构鉴定目标RNA时，有严格的多步骤控制，RNA解旋酶在此过程中可能起着至关重要的作用。
