Transglutaminase 2 (TG2) is a ubiquitously expressed (intracellular as well as extracellular) protein, with multiple modes of Post-translational regulation, including an allosteric disulfide bond between Cys-370-Cys-371 that renders the enzyme inactive in the extracellular matrix.
The endomysium contains a form of transglutaminase called "tissue transglutaminase" or "tTG" for short, and antibodies that bind to this form of transglutaminase are called endomysial autoantibodies (EmA). [6] The antiendomysial antibody test is a histological assay for patient serum binding to esophageal tissue from primate.
These enzymes can also deamidate glutamine residues to glutamic acid residues in the presence of water [1] Gln-(C=O)NH 2 + H 2 O → Gln-COOH + NH 3. Transglutaminase isolated from Streptomyces mobaraensis-bacteria for example, is a calcium-independent enzyme. Mammalian transglutaminases among other transglutaminases require Ca 2+ ions as a ...
The smallest digest of trypsin and chymotrypsin for the region is a 33mer. [1] This particular region has three tissue transglutaminase sites, two sites that lie within the 14 amino acid insertion, a region of maximal stimulation are found with more than 80% reduction in response for native, un-deaminated, sequence at the position. [26]
The absence of HLA-DQ2 and HLA-DQ8 has a very high negative predictive value for CD, [2] [67] and the predictive value can be further enhanced by including HLA-DQ7.5 (HLA-DQ2 and HLA-DQ8 are found in coeliac disease 98% of the time in Caucasians, HLA-DQ7.5 present in the remaining 1.6% and only 0.4% of Caucasians are missed with the combination ...

The IgG antibody is similar to AGA IgA, but is found at higher levels in patients with the IgA-less phenotype. It is also associated with coeliac disease and non-celiac gluten sensitivity. [5] [6] [7] Anti-gliadin antibodies are frequently found with anti-transglutaminase antibodies.
