TRIM63 and muscle atrophy: Well-accepted ‘atrogenes’, Atrogin-1 (Fbxo32) and Murf1 (Trim63) encoding muscle atrophy F-Box/atrogin-1 (MAFbx) and muscle-specific RING-finger protein 1 (MuRF1) belonging to ubiquitin–proteasomal pathway, are highly expressed in multiple models of muscle atrophy both in mRNA and protein levels [7].
