Tissue transglutaminase (abbreviated as tTG or TG2) is a 78-kDa, calcium-dependent enzyme (EC 2.3.2.13) of the protein-glutamine γ-glutamyltransferases family (or simply transglutaminase family).
In disease, transglutaminase reacts with gliadin forming a linkage. [21] In forming this bond transglutaminase becomes linked to T-cell epitopes on gliadin. B-cells with surface IgM that react to transglutaminase can present it with bound gliadin peptides to T-cells which stimulate B-cell maturation and proliferation to plasma cells making IgA ...
The core domain belongs to the papain-like protease superfamily (CA clan) and uses a Cys-His-Asp catalytic triad. [2] Protein 4.2, also referred to as band 4.2, is a catalytically inactive member of the human transglutaminase family that has a Cys to Ala substitution at the catalytic triad. [6]
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.

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.

Cytokine dysregulation – Cytokines have been recently divided into two groups according to the population of cells whose functions they promote: Helper T-cells type 1 or type 2. The second category of cytokines, which include IL-4, IL-10 and TGF-β (to name a few), seem to have a role in prevention of exaggeration of pro-inflammatory immune ...
