Architecture of RNA-RNA interactions

Area of Science:

• Molecular Biology
• Genetics
• Biochemistry

Background:

• RNA molecules form complex tertiary structures through intramolecular RNA-RNA interactions (RRIs).
• These RRIs are crucial for regulating gene expression, including transcription, RNA processing, and translation.
• RNAs, particularly noncoding RNAs, rely on intermolecular base pairing and RNA-binding proteins for regulatory specificity.

Purpose of the Study:

• To review technical advances and limitations of methodologies for studying cellular RRIs.
• To emphasize the emerging architectural roles of RRIs in gene regulation.

Main Methods:

• Discussion of various sequencing-based methods developed for studying cellular RRIs.
• Focus on methodologies for decoding both intramolecular and intermolecular RRIs.

Main Results:

• Recent sequencing-based methods have uncovered highly complex RRIs in mammalian cells.
• These methods provide insights into the structural organization and regulatory functions of RRIs.

Conclusions:

• Decoding RRIs is essential for understanding RNA architecture and its roles in development, differentiation, and disease.
• Further research into RRIs and associated methodologies will advance our understanding of gene regulation.
