The unannotated transcriptome. (A) An anti-intron transcript at the RPS18A locus. A select group of intron-containing genes displayed signal on the opposite (antisense) strand that correlated to the position of the intron. The segment opposite the intron has been termed the anti-intron. (B) An anti-intergenic junction transcript at the NDE2/SUB2 locus. A select group of closely spaced genes displayed signal on the opposite strand in the gap between the annotated genes. In this example, expression of the anti-intergenic junction correlates to a greater degree with expression from the upstream transcript, NDE2. (C) An anti-intergenic junction transcript at the MIG2/SIP2 locus. In contrast to B, this anti-intergenic junction segment correlates to a greater degree with expression from the downstream transcript, SIP2.
