Outline of Final Research Achievements

Our preliminary studies indicated GTRAP and EAAC1 are inversely regulated by miR96, but there is no miR96-binding site on GTRAP messenger RNA. We speculated the inhibition by miR96 is not achieved by a direct binding to GTRAP but is mediated through another unidentified protein. This protein has been identified by this project.
