Anti-OXCT1 antibodies are used in the immunodetection of the protein 3-oxoacid CoA-transferase 1. In humans, the canonical protein has a reported length of 520 amino acid residues and a mass of 56.2 kDa. Its subcellular localization is in the mitochondria. Alternative splicing is reported to yield 2 different isoforms for this protein. It is notably expressed in heart, followed in order by brain, kidney, skeletal muscle, and lung, whereas in liver it is undetectable. A member of the 3-oxoacid CoA-transferase protein family, it is known to be involved with adipose tissue development and brain development. Synonyms for this target antigen include SCOT, succinyl-CoA:3-ketoacid coenzyme A transferase 1, mitochondrial, 3-oxoacid CoA transferase, SCOT-s, and OXCT.
