Specificity Comments: Tissue transglutaminase (tTG) is a 75 kDa monomeric globular protein expressed in the majority of cells and tissues. tTG localizes mainly in the cytoplasm but some tGT is present on the cell surface and is association with the extracellular matrix. In addition to its guanosine triphosphatase (GTPase) activity, tTG catalyzes the posttranslational modification of proteins by transamidation of available glutamine residues. Extracellular tTG is able to bind to and cross-link several ECM proteins and may function to stabilize the ECM and basement membranes. The protein is translated as a fully active enzyme and there is no evidence for proteolytic activation. High constitutive expression and accumulation of active tTG is observed in (among others) endothelial cells, platelets, vascular smooth muscle cells and epithelial cells of the lens. tTG is expressed at very low levels in skeletal muscle cells and neurons and may be difficult to detect in these cell/tissue types.
Transglutaminase (TGase) catalyses the crosslink of proteins by forming e-(g-glutamyl) lysine isopeptide bonds and requires the binding of Ca2+ for its activity. In mammals, eight distinct TGase isoenzymes have been identified. Tissue transglutaminase (tTGase), also known as TGase 2, has four distinct domains: N-terminal b-sandwich, catalytic core and two C-terminal b-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 tTGase activity is manifested by polymerization of a number of proteins, including Ab peptide, b-amyloid precursor protein and the tau protein, with formation of neurofibrillary tangles.
