General Information

Biological Significance TG3 catalyzes the calcium-dependent formation of isopeptide cross-links between glutamine and lysine residues in various proteins, as well as the conjugation of polyamines to proteins.
Expression Expression levels are increased in relation to calcium ion concentration. Tissue and Cell Localization: TG3 proteins are widely distributed in the cytoplasm.
Implications in Disease Anti-transglutaminase antibodies are found in celiac disease and may play a role in the small bowel damage in response to dietary gliadin that characterises this condition.
Post-Translational Modifications TG3 is activated by proteolytic processing. In vitro activation is commonly achieved by cleavage with dispase, a neutral bacterial protease. Dispase cleavage site was proposed to lie between Ser-470 and Ser-471.
