This invention provides expressible polynucleotides, which can express a target protein or polypeptide. Synthetic mRNA constructs for producing a protein or polypeptide can contain one or more 5′ UTRs, where a 5′ UTR may be expressed by a gene of a plant. In some embodiments, a 5′ UTR may be expressed by a gene of a member of
Arabidopsis
genus. The synthetic mRNA constructs can be used as pharmaceutical agents for expressing a target protein or polypeptide in vivo.
这项发明提供了可表达的多核苷酸,可以表达目标蛋白质或
多肽。用于产生蛋白质或
多肽的合成mRNA构建物可以包含一个或多个5' UTR,其中5' UTR可以由植物的
基因表达。在某些实施例中,5' UTR可以由拟南芥属植物的
基因表达。这些合成mRNA构建物可以用作体内表达目标蛋白质或
多肽的药用剂。
