Proteomics is the large-scale study of proteins, focusing on their structure, function, and interactions within a biological context. This field involves techniques such as mass spectrometry and chromatography to identify and quantify proteins, uncover post-translational modifications, and analyse protein-protein interactions. By providing a comprehensive view of the protein content in cells, tissues, or organisms, proteomics enhances our understanding of biological processes, disease mechanisms, and potential therapeutic targets, offering insights that complement genomic and transcriptomic studies.
