    [Abstract]

    RNA-RNA and RNA-protein interactions are involved in the regulation of gene expression. Here, we describe an updated and extended version of our RNA purification and protein identification (RaPID) protocol for the pulldown of aptamer-tagged mRNAs by affinity purification. The method takes advantage of the high affinity interaction between the MS2

    [Abstract] Transfer RNAs (tRNAs) are heavily decorated with post-transcriptional modifications during their biosynthesis. To fulfil their functions within cells, tRNAs undergo a tightly controlled biogenesis process leading to the formation of mature tRNAs. In addition, functions of tRNAs are often modulated by their modifications. Although the biological ...
    Identification of RNase-sensitive LINE-1 Ribonucleoprotein Interactions by Differential Affinity Immobilization

    [Abstract] Long Interspersed Nuclear Element-1 (LINE-1, L1) constitutes a family of autonomous, self-replicating genetic elements known as retrotransposons. Although most are inactive, copious L1 sequences populate the human genome. L1s proliferate in a ‘copy-and-paste’ fashion through an RNA intermediate; a full-length L1 transcript is ~6,000 nucleotides ...
