TOMM40 (Translocase of Outer Mitochondrial Membrane 40) is a protein encoded by the TOMM40 gene. It is a key component of the outer mitochondrial membrane translocase complex, which is essential for the import of precursor proteins into mitochondria. This protein is embedded in the outer mitochondrial membrane and plays a crucial role in mitochondrial function and biogenesis. Research has shown that TOMM40 is involved in various cellular processes, including lipid metabolism and energy production. Additionally, it has been implicated in several diseases, such as cardiovascular system disease and Alzheimer's disease.
