Fluorescent RNAs: new opportunities for drug discovery

Area of Science:

• Biochemistry
• Molecular Biology
• Drug Discovery

Background:

• Fluorescent RNAs (FRs) are RNA mimics of fluorescent proteins (FPs).
• FRs and FR-derived biosensors (FRBs) enable RNA tagging and investigation of dynamics.
• FRBs are also utilized in point-of-care testing for diverse targets.

Purpose of the Study:

• To review advances in FRs and FRBs.
• To explore the application of FRs and FRBs in accelerating RNA and small-molecule drug discovery.
• To discuss current limitations and future directions for FR and FRB technologies.

Main Methods:

• Literature review of recent advances in FRs and FRBs.
• Analysis of studies demonstrating FR and FRB utility in drug discovery stages.
• Discussion of technological limitations and future research pathways.

Main Results:

• FRs and FRBs are increasingly used for RNA tagging and studying biological functions.
• FRBs show promise for point-of-care diagnostics.
• Emerging evidence suggests FRs and FRBs can accelerate various stages of drug discovery.

Conclusions:

• FRs and FRBs represent powerful tools with significant potential in drug discovery.
• Further development is needed to overcome current technological limitations.
