Anti-methylmalonyl-CoA mutase antibodies are used for the immunodetection of the protein encoded by the MMUT gene. In humans, the canonical protein has a reported length of 750 amino acid residues and a mass of 83.1 kDa. Its subcellular localization is in the mitochondria and cytoplasm. A member of the Methylmalonyl-CoA mutase protein family, it is known to catalyze the reversible isomerization of methylmalonyl-CoA (MMCoA) (generated from branched-chain amino acid metabolism and degradation of dietary odd chain fatty acids and cholesterol) to succinyl-CoA (3-carboxypropionyl-CoA), a key intermediate of the tricarboxylic acid cycle. Other names for this target antigen include MUT, methylmalonyl-CoA mutase, mitochondrial, methylmalonyl Coenzyme A mutase, methylmalonyl-CoA isomerase, and MCM. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of methylmalonyl-CoA mutase antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
