Post-translational Modifications in Brain Diseases: A Future for Biomarkers

Area of Science:

• Biochemistry
• Proteomics
• Neuroscience

Background:

• Biomarker panels traditionally use genetics and proteomics.
• Post-translational modifications (PTMs) are crucial for protein function and regulation.
• PTMs are often overlooked in standard proteomic analyses.

Purpose of the Study:

• To highlight the potential of PTMs in biomarker research for brain diseases.
• To compile existing knowledge on PTMs in neurological and psychiatric conditions.

Main Methods:

• Review and compilation of literature on PTMs in brain disease.
• Analysis of proteomic workflows and their limitations regarding PTM detection.

Main Results:

• PTMs significantly impact protein properties like binding, localization, activity, and stability.
• Underrepresentation of PTM data in current biomarker discovery pipelines.
• Brain diseases present unique challenges for diagnosis and prognosis, making novel biomarkers essential.

Conclusions:

• PTMs represent a valuable, untapped resource for developing improved diagnostic and prognostic biomarkers.
• Integrating PTM analysis into proteomic workflows can enhance understanding of brain diseases.
• Further research into PTMs holds significant promise for advancing medical treatments and patient outcomes.
