Research value of this Strain Many important biological processes, such as blood coagulation, are dependent on rapid cross-linking or "spotwelding". These reactions, which are catalysed by transglutaminases, endow the resulting structure with extra rigidity and resistance against proteolytic degradation. Having knowledge of these enzymes is essential for understanding diverse hereditary diseases of the blood and skin and various autoimmune, inflammatory and degenerative conditions. One such enzyme, tranglutaminase type 2 (TGM2) has been implicated in wound healing and in the pathogenesis of inflammatory disorders such as Crohn's disease, ulcerative colitis and coeliac disease as well as a number of important neurodegenerative diseases, such as Huntington's, Alzheimer's and progressive suprabulbar palsy. TG2 is unique among the transglutaminases because it is the only member shown to have functions other than cross-linking. The various functions of TG2 must be tightly coordinated. To better understand the function of TG2, we utilised homologous recombination to develop a floxed mouse line in which the TGM2 gene can be inactivated by Cre-mediated excision, either in the whole organism or in tissue-specific manner.
