Outline of Final Research Achievements |
Dopamine-beta-hydroxylase catalyzes conversion of dopamine to noradrenaline in the lumen of chromaffin granule of adrenal cortex. This enzyme requires ascorbic acid (vitamin C) as a cofactor. Previous studies indicated that ascorbic acid is accumulated in this granule. However, molecular mechanism of ascorbic acid transport to this granule was not understood yet. In this study, we tried to identify the transporter responsible to vesicular ascorbic acid accumulation and reveal molecular mechanism of ascorbic acid transport to the vesicle. We successfully identified the vesicular transport the is located in the chromaffin granule of adrenal cortex by PCR, immunohistochemistry and western blot analyses.
