UCSC browser snapshots show tracks from small and long RNA-seq analyses of mouse , bovine and porcine oocytes Tracks were constructed as described in material and methods. The y-scale for small RNAs depicts counts per million (CPM) of mapped 19-32 nt reads. The y-scale for long RNA-seq depicts CPM of mapped fragments. Grey rectangles and dashed lines represent exon-intron structure and transcript splicing inferred from RNA-seq data. Despite the splice acceptor of the terminal exon appears conserved, murine RNA-seq data do not support splicing of the primary miR-205 transcript. Instead, the mmu-miR-205 locus produces a detectable antisense spliced maternal lncRNA while the precursor of mmu-miR-205 is undetectable. SA, splice acceptor for the last exon of lncRNA originating from the locus.
