Posttranslational
Posttranslational refers to the modifications and alterations that occur to a protein after it has been synthesized from a ribosome. These modifications can include processes such as phosphorylation, glycosylation, acetylation, and cleavage, which can affect the protein's structure, function, and localization within the cell. Posttranslational modifications play a crucial role in regulating protein activity and signaling pathways in various cellular processes.
