Anti-CMBL antibodies are used in the immunodetection of the protein carboxymethylenebutenolidase homolog. In humans, the canonical protein has a reported length of 245 amino acid residues and a mass of 28 kDa. Its subcellular localization is in the cytoplasm. It is found to be widely expressed, with highest levels in the liver, followed by kidney, small intestine and colon. A member of the Dienelactone hydrolase protein family, CMBL is known to be involved with metabolic processes. Synonyms for this target antigen include carboxymethylenebutenolidase homolog (Pseudomonas) and carboxymethylenebutenolidase-like (Pseudomonas). CMBL gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some CMBL antibodies may have been used in research and have associated citations. ELISA and Western Blot are common applications for these antibodies.
