Selenium and GPX4, a vital symbiosis.

Selenium has transitioned from an environmental poison and carcinogen to an essential micronutrient associated with a broad array of health promoting effects. These beneficial effects are now accepted to be linked to its incorporation into selenoproteins, a family of rare proteins utilizing a specialized translation machinery to integrate selenium in the form of selenocysteine. Despite this recognized role, much less is known regarding the actual role of selenium in these proteins. Here, we will provide the reader with an overview of the essential role of specific selenoproteins and their link to pathology based on mouse studies and relevant mutations discovered in humans. Additionally, we will cover recent insights linking a non-interchangeable role for selenium in glutathione peroxidase 4 and its function in suppressing ferroptosis. This critical dependency ultimately generates a strong reliance on metabolic pathways that regulate selenium metabolism and its incorporation into proteins, such as the mevalonate pathway.
