The proteome is the entire set of proteins produced by a cell, tissue, or organism. It represents the complete structural and functional potential of an organism's genome at a specific point in time. Proteomics is the study of the proteome, including the identification and characterization of the proteins present in a sample, their functions, interactions, and modifications. Proteomics research aims to understand how proteins work together in biological processes, how they are regulated, and how their dysregulation can lead to disease. Techniques used in proteomics include mass spectrometry, protein separation techniques, and bioinformatics analysis.
