After four decades of extensive studies, the role of membrane-bound Translocator proteins (TSPOs) remains unclear and even controversial. In light of recent insights into the structure and activity of TSPOs, showing that they cannot only bind, but also enzymatically photodegrade protoporphyrin IX, we discuss their emerging physiological roles and regulation.
