Annotation and transcriptional profile of the horse PAB and XKR3Y. Schematic drawing of the region around horse PAB in both sex chromosomes showing the relative position of XKR3Y exons, functional elements, and other landmarks (not drawn to the scale); PAR-Y is presented shorter because of incomplete assembly in eMSYv3; an arrow above XKR3Y exon1 shows the start and direction of transcription; transcripts revealed by RT-PCR are shown below XKR3Y exons.
