Proteomics

Proteomics is the large-scale, systematic study of the complete set of proteins expressed by an organism, tissue, or cell under specific conditions, capturing a dynamic picture of biological function that the static genome cannot provide.

Overview

The discipline encompasses protein identification, quantification, characterization of post-translational modifications, three-dimensional structures, and protein–protein interaction networks; mass spectrometry and high-performance liquid chromatography are the primary analytical workhorses, generating datasets so large that computational biology and machine learning are essential for interpretation.

Why it matters

Proteomics bridges genetic information and biological function — revealing what an organism is actually doing rather than merely what it could do — and has enabled the discovery of biomarkers for cancers, neurodegenerative disorders, and cardiovascular disease that often appear long before clinical symptoms, profoundly advancing drug target identification and the understanding of drug resistance.
