简介：
Overview
This protocol outlines a method for studying mRNA translation regulation in poxvirus-infected cells using an in vitro transcribed RNA-based luciferase reporter assay. The assay allows for the examination of translation regulation by cis-elements of mRNA, including both the 5'-untranslated region (UTR) and 3'-UTR.
