Overview
Post translational modification (PTM) refers to the various chemical modifications that proteins undergo after translation, such as phosphorylation, ubiquitination, and glycosylation. These modifications can significantly impact protein function, localization, and interactions, and are crucial for regulating cellular processes like signal transduction, metabolism, and gene expression. With over 200 known types of PTMs, researchers like Dr. David Brautigan and Dr. Tony Hunter have made significant contributions to our understanding of PTM biology, including the discovery of key enzymes like kinases and phosphatases. The study of PTMs has also led to the development of new therapeutic strategies, such as kinase inhibitors, which have shown promise in treating diseases like cancer and Alzheimer's. However, the complexity and diversity of PTMs also pose significant challenges for researchers, including the need for more sophisticated analytical tools and a deeper understanding of PTM regulation and dynamics. As our knowledge of PTMs continues to grow, it is likely to have a major impact on our understanding of human disease and the development of new treatments, with a potential market size of over $10 billion by 2025, according to a report by Grand View Research.
