Abstract

The maintenance of muscle function is extremely important for whole body health and exercise is essential to this process. The ubiquitin-proteasome system (UPS) is required for muscle adaptation following exercise but little is known about acute posttranslational regulation and proteome remodeling during and after high-intensity exercise. Here, we used quantitative proteomics to study ubiquitin signaling dynamics in human skeletal muscle biopsies from healthy males before, during, and after a single bout of high-intensity exercise. Exercise resulted in a marked depletion of protein ubiquitylation in the vastus lateralis muscle consistent with proteasome activation. This was also associated w..
