Insights into functional modulation of catalytic RNA activity

Area of Science:

• Molecular Biology
• Biochemistry
• Genetics

Background:

• RNA molecules perform diverse functions beyond protein synthesis, including gene expression regulation via noncoding RNAs like micro-RNAs and riboswitches.
• The discovery of catalytic RNAs (ribozymes) has significantly impacted our understanding of life's molecular evolution.
• RNA's inherent ability to interact with and be modulated by various ions and molecules is a fundamental characteristic.

Purpose of the Study:

• To review representative examples of modulators that interact with catalytic RNAs.
• To illustrate the potential of catalytic RNAs as versatile tools and therapeutic targets in research and clinical settings.

Main Methods:

• This review synthesizes existing literature on RNA-modulator interactions.
• It focuses on examples demonstrating modulation of ribozyme activity, including inhibition, activation, and substrate-specificity alteration.

Main Results:

• Several classes of molecules and ions are shown to effectively modulate catalytic RNA activity.
• Modulation strategies can enhance ribozyme utility in translational research and clinical applications.

Conclusions:

• Catalytic RNAs are crucial regulators and evolutionary relics with significant therapeutic and research potential.
• Understanding RNA-modulator interactions is key to developing novel ribozyme-based tools and treatments.
