Post translational modifications are changes that occur to proteins after the synthesis of peptides. There are various types of PTMs, including phosphorylation, acetylation, glycosylation, and methylation, among others. These modifications are crucial in regulating protein function, stability, and localization. Some possible synonyms for post-translational modification include protein modification, protein processing, protein maturation, postranslational changes, and protein maturation. These terms describe the same process of modifying peptides after they are synthesized, and each term is used in different contexts depending on the field of study. Regardless of the terminology used, post-translational modifications represent a critical aspect of protein regulation that affects various cellular processes.
