Transglutaminase 1 and its regulator tazarotene-induced gene 3 localize to neuronal tau inclusions in tauopathies.

ABSTRACT: Alzheimer's disease (AD), progressive supranuclear palsy (PSP), frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17), and Pick's disease (PiD) are commonly known as tauopathies. Neurodegeneration observed in these diseases is linked to neuronal fibrillary hyperphosphorylated tau protein inclusions. Transglutaminases (TGs) are inducible enzymes, capable of modifying conformational and/or structural properties of proteins by inducing molecular cross-links. Both transglutaminase 1 (TG1) and transglutaminase 2 (TG2) are abundantly expressed in the brain and are associated with fibrillary hyperphosphorylated tau protein inclusions in neurons of AD, so-called neurofibrillary tangles (NFTs). However, other data obtained by our group suggested that tau pathology in the brain
