Here, we present practical considerations on the application of UV irradiation based methods to comprehensively determine in vivo RNA-protein interactions in Arabidopsis thaliana, focussing on individual nucleotide resolution crosslinking immunoprecipitation (iCLIP) and mRNA interactome capture. In addition to the common cells, model organisms, etc., Profacgen's eCLIP-seq can perform most of the. We have a variety of proven antibodies, such as FLAG, MYC, etc. To assess the efficiency of iCLIP library construction, we used irCLIP-adaptor. This has only recently been successfully applied to plants. Librariums generated using the eCLIP-Seq approach are typically sequenced using standard SE50 or SE75 conditions on Illumina HiSeq or Novaseq. Green stars denote internal IR800CW dye and orange ovals 3 biotin modification. RNA immunoprecipitation and biotin pull-down assays were used to identify the UNR target mRNAs in glioma cells. State-of-the-art techniques to determine RNA-protein interactions genome-wide in animals are based on the covalent fixation of RNA and protein in vivo by UV light. Then, the candidate UNR target mRNAs were identified by analyzing the sequencing data of UNR iCLIP-seq, RNA sequencing and ribosome profiling databases of human melanoma.

In turn, while numerous RNA-binding proteins have been identified through mutant analysis and homology-based searches in plants, only recently a full compendium of proteins with RNA-binding activity has been experimentally determined for the reference plant Arabidopsis thaliana. This is not least due to technical challenges in plants.

While the regulatory interactions between proteins and RNA are well understood in animals, until recently little information was available on the global binding landscape of RNA-binding proteins in higher plants. RNA-binding proteins are key players that interact specifically with mRNAs to co-ordinate their fate. This study describes the development of ‘in vitro iCLIP’ for the study of how proteinRNA interactions are determined by cis -acting sequences and modulated by trans -acting RBPs. Post-transcriptional regulation makes an important contribution to adjusting the transcriptome to environmental changes in plants. In vitro iCLIP-based modeling uncovers how the splicing factor U2AF2 relies on regulation by cofactors.
