Chemical Probes For Protein Α-N-Terminal Methylation, Brianna D. Mackie

Theses and Dissertations

While protein α-N-terminal methylation has been known for nearly four decades since it was first uncovered on bacteria ribosomal proteins L33, the function of this modification is still not entirely understood. Recent discoveries have demonstrated α-N-terminal methylation is essential to stabilize the interactions between regulator of chromosome condensation 1 (RCC1) and chromatin during mitosis, to localize and enhance the interaction of centromere proteins (CENPs) with chromatin, and to facilitate the recruitment of DNA damage-binding protein 2 (DDB2) to DNA damage foci. Identification of N-terminal methyltransferase 1 (NTMT1) unveiled the eukaryotic methylation writer for protein α-N-termini. In addition, NTMT2 that shares …

The existence of thrombosis in numerous pathophysiological situations formed a vast necessity for anticoagulation therapy. Thrombin and factor Xa are the only two factors of the entire coagulation cascade that have been major targets for regulation of clotting via the direct and indirect mechanism of inhibition. Our recent discovery of sulfated non-saccharide glycosaminoglycan …
