Identification of the MuRF1 Skeletal Muscle Ubiquitylome Through Quantitative Proteomics
{{output}}
MuRF1 (TRIM63) is a muscle-specific E3 ubiquitin ligase and component of the ubiquitin proteasome system. MuRF1 is transcriptionally upregulated under conditions that cause muscle loss, in both rodents and humans, and is a recognized marker of muscle atrophy. ... ...
