Degradomics is a relatively new field of study, focused on characterizing protein degradation pathways and identifying their associated molecular signatures. Synonyms for degradomics include proteome degradation, protein catabolism, and proteostasis. Proteome degradation refers to the breakdown of proteins within a cell or organism. Protein catabolism involves the breakdown of proteins into smaller units, such as amino acids, for use in various metabolic processes. Proteostasis is the process by which cells maintain proper protein folding, trafficking, and degradation. These terms all refer to the complex and interrelated processes involved in regulating protein degradation, and are essential for maintaining cell health and function.
