| Research Abstract |
The protein cross-links in the stratum corneum include Gln-Lys and SS bonds. In the present study, in combination of the high resolution fluorescent imaging for in situ transglutaminase activity and SS bonds with immunofluorescence, we showed that those cross-links are formed in order in the keratinization process to reinforce the structure of the stratum corneum. Furthermore, we demonstrated that transglutaminase 1 is inevitable for the proper localization of SS in the stratum corneum using mutant mice in transglutaminase 1.
