Characterization Of The Substrate Interactions And Regulation Of Protein Arginine Methyltransferase, Yalemi Morales

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Protein arginine methylation is a posttranslational modification catalyzed by the family of proteins known as the protein arginine methyltransferases (PRMTs). Thousands of methylated arginines have been found in mammalian cells. Many targets of arginine regulation are involved in important cellular processes like transcription, RNA transport and processing, translation, cellular signaling, and DNA repair. Since PRMT dysregulation has been linked to a variety of disease states, understanding how the activity of the PRMTs is regulated is of paramount importance. PRMT1 is the predominant PRMT, responsible for about 85% of all arginine methylation in cells, but very little is known about how …
