Disease relevance of MTM1


High impact information on MTM1

  • The bulk of mitochondrial iron is normally unavailable to SOD2, but when mitochondrial iron homeostasis is disrupted, for example, by mutations in S. cerevisiae mtm1, ssq1 and grx5, iron accumulates in a reactive form that potently competes with manganese for binding to SOD2, inactivating the enzyme [2].
  • Our studies suggest a connection with SOD2, and we have named the yeast gene MTM1 for manganese trafficking factor for mitochondrial SOD2 [3].
  • Surprisingly, the mitochondrial organelle of mtm1 Delta mutants shows no deficiency in manganese levels [3].
