TRIM32 and muscular dystrophy: With special attention to muscle maintenance in terms of regeneration and atrophy, this review is focused on the roles of TRIM32 and its E3 ubiquitin ligase activity in skeletal muscle; specifically, TRIM32-interacting proteins in skeletal muscle, expression levels of TRIM32 under various conditions, such as cellular senescence and terminal differentiation, and patients with muscular dystrophies and atrophies due to LGMD2H.
