Synopsis

Protein termini represent a major route to protein regulation. From the moment the very first amino acid of a polypeptide chain exits the ribosome there is potential for steering from the cellular environment. This volume of Methods in Enzymology Modifications and Targeting of Protein Termini focuses on Protein N-termini and C-termini and their modifications which include acetylation, arginylation, myristoylation and oxidation. Also, the impact of terminal modifications is covered, in particular the impact on protein turnover and the ubiquitin E3 ligases which specifically recognize protein N-termini (N-degrons) and C-termini (C-degrons). In addition to the detailed methods and laboratory protocols, the chapters include informative overviews and reviews of the different subfields.

• Provides the authority and expertise of leading contributors from an international board of authors
• Includes the latest information on modifications and targeting of proteins via their N- and C-terminal ends
• Presents a broad spectrum of methods within protein acetylation, myristoylation, arginylation and oxidation

About this title

About the Author

Professor Thomas Arnesen received his Ph.D. in molecular biology from the University of Bergen, Norway in 2006. After postdoctoral work at Haukeland University Hospital and University of Rochester Medical Center, he established his own lab at the University of Bergen in 2010. His main interest has been protein N-terminal acetylation and the responsible enzymes, the N-terminal acetyltransferases (NATs). Using Saccharomyces cerevisiae and human cell models combined with in vitro approaches his lab and collaborators have i) identified and defined the presumed complete cytosolic human NAT-machinery including NATs acting post-translationally, ii) quantitatively analysed the N-terminal acetylomes of yeast and human cells, iii) developed novel assays for NAT-profiling, iv) gained mechanistic insights of the molecular and cellular effects of N-terminal acetylation, v) contributed to the understanding of the physiological and clinical importance of NATs by revealing the links between NatA and cancer cell survival and drug sensitisation, and lately by defining genetic disorders caused by pathogenic NAT variants. The Arnesen lab also contributed to solving the first NAT-structures and developing the first potent NAT-inhibitors.

With Fred Sherman and Bogdan Polevoda, Arnesen introduced the NAA (N-alpha acetyltransferase) nomenclature of the N-terminal acetyltransferase genes and proteins, and he acts as the specialist advisor for the HUGO Gene Nomenclature Committee for these genes. Arnesen is one of the founders and council members of the International Society of Protein Termini (ISPT). He has organized several symposia on N-terminal acetylation, and in 2022 he was the head organizer of the EMBO Workshop ‘Protein Termini – From mechanism to biological impact’ in Bergen, Norway. Arnesen has co-authored more than 100 peer-reviewed publications. Today he is head of the Translational Cell Signaling and Metabolism group at the Dept. of Biomedicine, UiB, supported by the Research Council of Norway and ERC. Here his team continues the basic and translational research to understand the impact of protein N-terminal modifications.
