Abstract
AMP-activated protein kinase (AMPK) is a key regulator of metabolism and a recognised target for the treatment of metabolic diseases such as Type 2 diabetes (T2D). Here, we review how mass spectrometry (MS) can be used to study short-term control by AMPK via protein phosphorylation and long-term control due to changes in protein expression. We discuss how MS can quantify AMPK subunit levels in tissues from different species. We propose hydrogen-deuterium exchange (HDX)-MS to investigate molecular mechanisms of AMPK activation and thermoproteomic profiling (TPP) to assess off-target effects of pharmacological AMPK activators/inhibitors. Lastly, because large MS data sets are generated, we consider different approaches that can be used for their interpretation.
期刊介绍：
Essays in Biochemistry publishes short, digestible reviews from experts highlighting recent key topics in biochemistry and the molecular biosciences. Written to be accessible for those not yet immersed in the subject, each article is an up-to-date, self-contained summary of the topic.
Bridging the gap between the latest research and established textbooks, Essays in Biochemistry will tell you what you need to know to begin exploring the field, as each article includes the top take-home messages as summary points.
Each issue of the journal is guest edited by a key opinion leader in the area, and whether you are continuing your studies or moving into a new research area, the Journal gives a complete picture in one place.
Essays in Biochemistry is proud to publish Understanding Biochemistry, an essential online resource for post-16 students, teachers and undergraduates. Providing up-to-date overviews of key concepts in biochemistry and the molecular biosciences, the Understanding Biochemistry issues of Essays in Biochemistry are published annually in October.
