    Abstract: PROBLEM TO BE SOLVED: To provide a screening assay, a compound, and a method for altering gene expression and the level of protein, particularly, an assay for screening for an agent modulating UTR-dependent gene expression and an agent modulating gene expression. SOLUTION: A nucleic acid construct comprises a high-level mammalian expression vector, an intron, and a nucleic acid sequence encoding a reporter polypeptide, wherein the nucleic acid sequence encoding a reporter polypeptide is proximally linked to a target untranslated region (UTR). The method includes: providing a cell having the nucleic acid construct comprising a high-expression, constitutive promoter upstream from a target 5' UTR; bringing the cell into contact with a compound; producing a nucleic acid molecule that contains a nucleic acid sequence encoding a reporter polypeptide and does not contain UTR not found in a target gene; and detecting the reporter polypeptide.
