Anti-BCKDK antibodies are used in the immunodetection of the protein branched chain keto acid dehydrogenase kinase. In humans, the canonical protein has a reported length of 412 amino acid residues and a mass of 46.4 kDa. Its subcellular localization is in the mitochondria. Up to 3 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the PDK/BCKDK protein kinase protein family, BCKDK is known to catalyze the phosphorylation and inactivation of the branched-chain alpha-ketoacid dehydrogenase complex, the key regulatory enzyme of the valine, leucine and isoleucine catabolic pathways. Synonyms for this target antigen include BDK, 3-methyl-2-oxobutanoate dehydrogenase [lipoamide] kinase, mitochondrial, BCKD-kinase, BCKDHKIN, and BCKDKD. BCKDK gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of BCKDK antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
