– OSMR is targeted to the mitochondrial matrix via the presequence translocase-associated motor complex components, mtHSP70 and TIM44. OSMR interacts with NADH ubiquinone oxidoreductase 1/2 (NDUFS1/2) of complex I and promotes mitochondrial respiration. Deletion of OSMR impairs spare respiratory capacity, increases reactive oxygen species, and sensitizes BTSCs to IR-induced cell death. OSMR Protein, Cynomolgus, Recombinant (His) is expressed in HEK293 mammalian cells with C-His tag. The predicted molecular weight is 82.04 kDa and the accession number is A0A2K5UFW5.
