Posttranslaatiivisista

Posttranslaatiivisista, also known as posttranslational modifications, are chemical alterations that occur after a protein has been translated from messenger RNA (mRNA) into a polypeptide chain. These modifications are crucial for the proper folding, stability, and function of proteins. They can occur on various amino acids within the protein sequence and include a wide range of chemical reactions, such as phosphorylation, glycosylation, acetylation, and ubiquitination. Posttranslational modifications play significant roles in various biological processes, including signal transduction, protein localization, and enzyme regulation. They are also involved in the development of diseases, such as cancer and neurodegenerative disorders, making them important targets for pharmaceutical research. The study of posttranslational modifications is a dynamic and rapidly evolving field in molecular biology and biochemistry.
