Transglutaminase (TGase) catalyses the crosslink of proteins by forming epsilon-(Upsilon-glutamyl) lysine isopeptide bonds and requires the binding of Ca2+ for its activity. In mammals, eight distinct TGase isoenzymes have been identified.Tissue transglutaminase (tau TGase), also known as TGase 2, has four distinct domains: N-terminal beta-sandwich, catalytic core and two C-terminal beta-barrel domains. tTGase may have a role in cell death, cell proliferation, cell differentiation, and receptor-mediated endocytosis. In the Alzheimer's disease brain, the elevated tau TGase activity is manifested by polymerization of a number of proteins,including A-beta peptide, beta-amyloid precursor protein and the tau protein, with formationof neurofibrillary tangles.
