Engineered Group I Ribozymes as RNA-Based Modular Tools to Control Gene Expression

  • Yoshiya Ikawa
  • Shigeyoshi Matsumura


Group I ribozymes (RNA enzymes) constitute a class of structural RNAs that promote cleavage and ligation of phosphodiester bonds to conduct RNA splicing. As naturally occurring group I ribozymes are constitutively active in most cases, modular engineering is required to apply them to control gene expression. We first introduce exceptional examples of modified splicing reactions of group I ribozymes. We then summarize strategies to engineer group I ribozymes to develop genetic modular tools and also their application to gene expression control.
