Proteomics

Proteomics is the large-scale study of the structure, expression, post-translational modifications, and interactions of the complete set of proteins produced by an organism, tissue, or cell. It investigates dynamic biological processes that cannot be inferred from genomic sequences alone.

Overview

The discipline encompasses protein identification, quantification, post-translational modification profiling, three-dimensional structural analysis, and interaction networks. Mass spectrometry and liquid chromatography serve as primary analytical platforms, generating extensive datasets that require computational biology and machine learning for interpretation.

Why it matters

Proteomics connects genetic information to functional cellular activity by revealing expressed protein states. It supports the identification of biomarkers across cancers, neurodegenerative disorders, and cardiovascular conditions while aiding drug target identification and the study of drug resistance.
