The role of FIS1 and its post-translational modifications in diseases and health damage caused by environmental pollution

Mitochondrial fission protein 1 (FIS1) is present in the cytoplasm and can be transported to the outer mitochondrial membrane. It can interact with DRP1 (Dynamin-Related Protein 1) to mediate mitochondrial fission and fusion, and most of the studies on FIS1 have centered on FIS1-DRP1 mitochondrial fission. However, more and more studies are now showing that FIS1 is not only involved in mitochondrial fission, but also plays a role in mitophagy, peroxisomal dynamics, and lysosomes. Post-translational modification (PTM) of proteins enables proteins to perform distinct functions and exhibit diverse properties, thereby creating multiple possibilities for many proteins. The post-translational modification of FIS1 protein is associated with the occurrence of many diseases. Environmental pollution has become a serious public health problem that affects people's health. The role of FIS1 in human health caused by environmental pollutants is worth in-depth study and exploration.
