Outline of Final Research Achievements

Matriptase is a transmembrane serine protease. In this study, we found that low-density lipoprotein receptor class A domain repeat in the stem domain of matriptase acts to enhance its zymogen activity and that some kinds of divalent cations are required for the expression of zymogen activity. In addition, we obtained evidence supporting that the activation of matriptase zymogen occurs by a mechanism requiring the interaction of the two molecules (transactivation).
