RNA: interactions drive functionalities

Area of Science:

• Molecular Biology
• Genomics
• Biochemistry

Background:

• Most human genomic sequences produce RNA, but only a fraction has known functions.
• RNA molecules engage in complex interactions with DNA, proteins, and other molecules, forming intricate networks.
• These interactions are fundamental to cellular processes.

Purpose of the Study:

• To categorize diverse RNA functions based on their interaction types with other macromolecules.
• To elucidate the roles of RNA in fundamental biological processes.

Main Methods:

• Review of existing literature on RNA interactions and functions.
• Classification of RNA functions by interaction partners (RNA, DNA, proteins, lipids, metabolites).

Main Results:

• RNAs participate in information flow, storage, environmental sensing, signal transduction, and gene regulation.
• RNAs can act as catalysts or inhibitors, modulating biological processes.
• RNA interactions are implicated in disease etiology and phenotypic variations.

Conclusions:

• RNA's functional versatility is primarily defined by its diverse molecular interactions.
• Understanding RNA-macromolecule interactions offers potential for clinical applications and understanding disease.
• Further research into RNA interactions can reveal novel therapeutic targets.
