| Research Abstract |
Vitamin K is a cofactor for γ-glutamyl carboxylase (GGCX), which catalyses the post-translational modifications of several vitamin K-dependent proteins, such as coagulation factors, osteocalcin and matrix Gla protein. We recently confirmed that the PK to MK-4 conversion took place in slice culture of mouse cerebra and primary culture of mouse cerebral hemispheres. Moreover, we identified MK-4 biosynthetic enzyme [UbiA prenyltransferase domain containing 1 (UBIAD1)]. In this study, we analyzed the function of MK-4 biosynthetic enzyme in brain and the relationship of vitamin K and neurodegenerative disease. As a result, we indicated that MK-4 and MK-4 biosynthetic enzyme may have a important rule in brain.
