TY - JOUR T1 - SpliceV: Analysis and publication quality printing of linear and circular RNA splicing, expression and regulation JF - bioRxiv DO - 10.1101/509661 SP - 509661 AU - Nathan Ungerleider AU - Erik Flemington Y1 - 2019/01/01 UR - http://biorxiv.org/content/early/2019/01/02/509661.1.abstract N2 - In eukaryotes, most genes code for multiple transcript isoforms that are generated through the complex and tightly regulated process of RNA splicing. Despite arising from identical precursor transcripts, alternatively spliced RNAs can have dramatically different functions. Transcriptome complexity is elevated further by the production of circular RNAs (circRNAs), another class of mature RNA that results from the splicing of a downstream splice donor to an upstream splice acceptor. While there has been a rapid expansion of circRNA catalogs in the last few years through the utilization of next generation sequencing approaches, our understanding of the mechanisms and regulation of circular RNA biogenesis, the impact that circRNA generation has on parental transcript processing, and the functions carried out by circular RNAs remains limited. Here, we present a visualization and analysis tool, SpliceV, that rapidly plots all relevant forward-and back-splice data, with exon and single nucleotide level coverage information from RNA-seq experiments in a publication quality format. SpliceV also integrates analysis features that assist investigations into splicing regulation and transcript functions through the display of predicted RNA binding protein sites and the configuration of repetitive elements along the primary transcript. SpliceV is compatible with both Python 2.7 and 3+, and is distributed under the GNU Public License.
