Background:

• Micropeptides, encoded by small open reading frames (sORFs), are emerging functional molecules.
• Their small size, low abundance, and antibody generation difficulties present significant research challenges.

Purpose of the Study:

• To systematize modern identification and functional characterization approaches for micropeptides.
• To highlight challenges and future directions in micropeptide research.

Main Methods:

• Bioinformatic algorithms for discovery.
• Ribosome profiling for global translation analysis.
• Mass spectrometry-based proteomics for direct detection.
• Phenotypic screenings for functional insights.
• Genetic knockouts and affinity tagging for mechanistic studies.

Main Results:

• Identified key strategies for micropeptide discovery and functional validation.
• Highlighted the utility of multi-omics approaches for comprehensive micropeptidome mapping.

Conclusions:

• Integrated multi-omics strategies are crucial for advancing micropeptide research.
• Overcoming methodological hurdles is essential for fully understanding micropeptide functions.
