  • Publication number: 20140370545
    Abstract: Described herein are rules to modify natural mRNAs or to engineer synthetic mRNAs to increase their translation efficiencies. These rules describe modifications to mRNA coding and 3? UTR sequences intended to enhance protein synthesis by: 1) decreasing ribosomal diversion via AUG or non-canonical initiation codons in coding sequences, and/or 2) by evading miRNA-mediated down-regulation by eliminating one or more miRNA binding sites in coding sequences.
    Type: Application

  • Publication number: 20090093049
    Abstract: Provided are methods of identifying oligonucleotides having transcriptional or translational activity by integrating ilie oligonucleotide into a eukaryotic cell genome such that the oligonucleotide is operatively linked to an expressible polynucleotide, and detecting a change in expression of the expressible polynucleotide due to the operatively linked oligonucleotide. Also provided are vectors useful for identifying an oligonucleotide having transcriptional or translational regulatory activity according to a method of the invention. In addition, isolated synthetic transcriptional or translational regulatory elements identified according to a method of the invention are provided, as are kits, which contain a vector useful for identifying a transcriptional or translational regulatory element, or an isolated synthetic transcriptional or translational regulatory element or plurality of such elements. Also provided are isolated transcriptional regulatory elements.

  • Patent number: 7468275
    Abstract: Synthetic and isolated translational regulatory elements, including oligonucleotides that have translational enhancing activity, internal ribosome entry site (IRES) activity, or translational inhibitory activity, and multimers of such translational regulatory elements are provided. In addition, compositions that include such translational regulatory elements are provided, as are methods of using the translational regulatory elements.
