Abstract

""Transglutaminases (TGs; E.C. 2.3.2.13) are ubiquitous. enzymes which catalyze post-translational modifications. of proteins. TGs and TG-catalyzed post-translational. modifications of proteins have been shown to be involved. in the molecular mechanisms responsible for several. human diseases. In particular, TG activity has been. hypothesized to also be involved also in the molecular. mechanisms responsible for human neurodegenerative. diseases. In support of this hypothesis, Basso et al. recently demonstrated that the TG inhibition protects. against oxidative stress-induced neuronal death, suggesting. that multiple TG isoforms participate in oxidative. stress-induced cell death and that nonselective TG. isoform inhibitors will be most effective in fighting oxidative. death in neurological disorders.
