Investigating The Importance Of The N-Terminal Negative Residues In Human Prmt1, Brooke Siler

Undergraduate Honors Capstone Projects

Many essential physiological pathways, such as cell proliferation, gene expression, and cardiovascular health are regulated by Protein Arginine Methyltransferases (PRMTs) through methylation of arginine residues in protein substrates. Understanding how PRMTs interact with their substrates is pivotal to understanding the biological role of these enzymes, and fundamental to the goal of identifying possible sites to be inhibited through drug therapy. Natural variations in the N-terminus of the PRMTl enzymes and data collected in our lab suggest that the N-terminus is important for activity and/or the binding of protein substrates. Preliminary data collected had led us to hypothesize that the negatively …
