Anti-ABAT antibodies are used in the immunodetection of the protein 4-aminobutyrate aminotransferase. In humans, the canonical protein has a reported length of 500 amino acid residues and a mass of 56.4 kDa. Its subcellular localization is in the mitochondria. It is notably widely expressed in many tissue types. A member of the Class-III pyridoxal-phosphate-dependent aminotransferase protein family, ABAT is known to catalyze the conversion of gamma-aminobutyrate and L-beta-aminoisobutyrate to succinate semialdehyde and methylmalonate semialdehyde, respectively. Synonyms for this target antigen include GABAT, NPD009, 4-aminobutyrate aminotransferase, mitochondrial, (S)-3-amino-2-methylpropionate transaminase, 4-aminobutyrate transaminase, and GABA-AT. ABAT gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of ABAT antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
