    • PROBLEM TO BE SOLVED: To provide compositions and methods related to mRNA translational enhancer elements that are sequence elements capable of promoting cap-dependent mRNA translation.SOLUTION: Provided is a cloning or expression vector comprising a transcription promoter, a polynucleotide sequence coding for a polypeptide having a eukaryotic translation initiation codon operably linked to the transcriptional promoter, a 5' untranslated sequence located between the transcriptional promoter and the eukaryotic translation initiation codon, and a translational enhancer polynucleotide located in the 5' untranslated sequence, the translational enhancer polynucleotide comprising one or more of a plurality of mRNA translational enhancer elements (TEEs) having a particular sequence, their variants, homologs, or functional derivatives. Also provided is a eukaryotic host cell comprising the cloning or expression vector.
    • 要解决的问题:提供与能够促进帽依赖性mRNA翻译的序列元件的mRNA翻译增强子元件相关的组合物和方法。解决方案:提供了包含转录启动子,编码多肽的多核苷酸序列的克隆或表达载体 具有可操作地连接到转录启动子的真核翻译起始密码子,位于转录启动子和真核翻译起始密码子之间的5'非翻译序列,以及位于5'非翻译序列中的翻译增强子多核苷酸,所述翻译增强子多核苷酸包含一个或多个 多个具有特定序列的mRNA翻译增强子元件(TEE),其变体,同系物或功能性衍生物。 还提供了包含克隆或表达载体的真核宿主细胞。
