Research Abstract

Localization and translational control of cytoplasmic mRNAs play key roles in the regulation of site and timing of gene expression. We analyzed molecular mechanisms by which localization and translational control of cyclin B1 mRNA deposited in oocytes are regulated using transgenes and real-time imaging of the site and timing of translation. In this study, we revealed that a cis-acting element consisting of 9 nucleotides sequences in the coding region is necessary for the regulation of both localization and translational control of the mRNA. Our results suggest a functional link between mRNA localization and translational control.
