Mitsugumin 53 (MG53), also known as Trim72, is a conservative member of TRIM family and is highly expressed in mouse skeletal and cardiac muscle, with very small amounts in humans. MG53 has been proved to be involved in the repair of cell membrane damage and has a protective effect on I/R injury in multiple oxygen-dependent organs, such as heart, brain, lung, kidney and liver. Recombinant human MG53 also plays a unique role in I/R, sepsis and other aspects, which is expected to provide new ideas for related treatment. This article briefly reviews the pathophysiology of I/R injury and the mechanism by which MG53 mitigates multi-organ I/R injury.
