Anti-ETFBKMT antibodies are used in the immunodetection of the protein electron transfer flavoprotein subunit beta lysine methyltransferase. In humans, the canonical protein has a reported length of 262 amino acid residues and a mass of 29.5 kDa. Its subcellular localization is in the mitochondria and cytoplasm. A member of the ETFBKMT protein family, ETFBKMT is reported to be a protein-lysine methyltransferase that selectively trimethylates the flavoprotein ETFB in mitochondria. Synonyms for this target antigen include ETFB lysine methyltransferase, methyltransferase like 20, methyltransferase-like protein 20, and electron transfer flavoprotein beta subunit lysine methyltransferase. ETFBKMT gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are common applications for ETFBKMT antibodies.
