Zonula occludens, in deutscher Literatur auch „Schlussleiste“) sind schmale Bänder aus Membranproteinen, die Epithelzellen von Wirbeltieren vollständig umgürten und mit den Bändern der Nachbarzellen in enger Verbindung stehen. The read spans an exon junction, meaning that it is derived from two exons, meaning that it's not mapping in one location in the genome but will be a 'split read'.
