Name: Summary of the probe development effort to identify inhibitors of Methionine sulfoxide reductase A (MSRA).
Oxidative damage, resulting from the production of reactive oxygen species (ROS) within cells, is believed to be a major factor in age-related diseases and the aging process. One of the mechanisms by which this damage occurs is via oxidation of methionine residues to methionine sulfoxide (Met(O)) derivatives in cellular proteins, which can lead to protein inactivation (1). These Met(O) species can be repaired/reduced by the thioredoxin (Trx)-dependent (2, 3) action of Methionine sulfoxide reductase A (MSRA) (4, 5). MSRA can reduce both free and protein-bound Met(O), and is highly expressed in oxidant-sensitive tissues such as kidney (6), neurons (7), liver(8), retinal epithelial cells (9), and macrophages (10). Each round of methionine oxidation and reduction by the MSRA system destroys one equivalent of ROS (11). Importantly, the action of MSRA has been shown to prevent irreversible oxidative protein damage and extend life span of both flies and yeast (12-14). As a result, the identification of compounds that modulate MSRA activity could have therapeutic value for cardiovascular (15, 16), neurodegenerative, lung (17), and eye diseases (18) involving oxidative damage. Similarly, because MSRA is found in virtually all species (19), and the catalytic mechanism has been elucidated (1, 20, 21), the identification of chemical tools that modulate MSRA would help elucidate its function and activation in cells, and may lead to useful tools to extend lifespan and reduce aging-related diseases (11).
