Rapid discovery of functional RNA domains

Area of Science:

• Molecular Biology
• Biochemistry
• RNA Therapeutics

Background:

• Identifying functional RNA motifs within large libraries is challenging.
• Current methods for RNA enrichment and analysis are often time-consuming and biased.

Purpose of the Study:

• To develop a novel technique for isolating minimal active RNA segments.
• To overcome limitations of sequence and structure bias in RNA analysis.
• To accelerate the discovery of functional RNA domains.

Main Methods:

• Developed a technique for truncating RNA sequences at 5' and 3' ends.
• Introduced independent primer-binding sequences to reduce bias.
• Applied the method to genomic and synthetic aptamers.

Main Results:

• Successfully isolated minimal active RNA segments from heterogeneous pools.
• Demonstrated the method's ability to reveal multi-stranded active RNAs.
• Facilitated the discovery of RNA structures for cellular sensors.

Conclusions:

• The developed technique provides a streamlined pipeline for defining active RNA domain boundaries.
• This approach significantly accelerates the discovery of novel functional RNAs.
• Enables the development of complex RNA structures like heterodimers for biotechnological applications.
