Post-translational Modifications

Post-Translational Modifications (PTMs) are biochemical changes that occur in proteins after their translation from mRNA into protein. PTMs are essential for the function of proteins and play a key role in cellular processes. Examples of PTMs include glycosylation, phosphorylation, acetylation, and cleavage. These changes are responsible for the structure and stability of proteins as well as their localization inside and outside of the cell, and their activity and interactions with other molecules. PTMs are important in many biological processes, such as immune response, signal transduction, and gene regulation. They also have implications for health, including the development of cancer, diabetes, and Alzheimer’s disease. Understanding PTMs is essential for the development of new therapies and drugs that target these modifications to treat diseases.
