Notes: OMA1 is an ATP-independent metalloproteinase encoded by OMA1.{35969} It is localized to the mitochondrial inner membrane and is comprised of a matrix-facing N-terminal domain, a transmembrane domain, and a C-terminal M48 metallopeptidase domain that is exposed to the intermembrane space.{35969,35970} Under various stress conditions, including oxidative stress, heat stress, and mitochondrial membrane depolarization, OMA1 is activated and cleaves long isoforms of the GTPase optic atrophy 1 (OPA1) at the S1 cleavage site, leading to inhibition of mitochondrial fusion and increased mitochondrial fragmentation.{35969,35970,47769} Under stress conditions, OMA1 is also autocatalytically degraded, thereby limiting, and allowing for reversal of, the stress response.{35970,47769} Oma1-/- mouse embryonic fibroblasts exhibit a loss of mitochondrial fragmentation upon exposure to hydrogen peroxide.{35970} Mice lacking Oma1 exhibit impaired thermogenesis, increased hepatic steatosis and serum triglyceride levels, and high-fat diet-induced obesity.{47770} Cayman’s Metalloendopeptidase OMA1 (human, recombinant) can be used for Western blot and ELISA applications.
