Z-RNA是RNA的一种高能左手构象,其功能仍然难以捉摸。越来越多的工作暗示了Z-RNA在免疫反应中的调节作用。在这里,我们回顾了如何Z-RNA功能存在于细胞RNA,特别是含有逆转录元件,可以识别的一个家庭的翼螺旋蛋白,对宿主防御的影响。我们还讨论了特定Z接触氨基酸的突变如何破坏其稳定Z-RNA的能力,导致功能丧失。最后,我们强调了该领域的知识差距,如果得到解决,将大大推进这一活跃的研究领域。
Z-RNA is a higher-energy, left-handed conformation of RNA, whose function has remained elusive. A growing body of work alludes to regulatory roles for Z-RNA in the immune response. Here, we review how Z-RNA features present in cellular RNAs—especially containing retroelements—could be recognized by a family of winged helix proteins, with an impact on host defense. We also discuss how mutations to specific Z-contacting amino acids disrupt their ability to stabilize Z-RNA, resulting in functional losses. We end by highlighting knowledge gaps in the field, which, if addressed, would significantly advance this active area of research.
