RNA transcription and degradation of Alu retrotransposons depends on sequence features and evolutionary history
Ontology highlight
ABSTRACT: Our work sheds light on the metabolism of RNA transcripts derived from genomic Alu repeats. Since it is unclear whether Alu elements are transcribed mainly by RNA polymerase II or III, we conducted a transcription shutoff experiment and metabolic RNA labeling. We find that Alu transcripts are as stable as mRNAs and originate in part from RNA polymerase II. Furthermore, we use the de Bruijn graph of all Alu sequences to discover sequence features that match transcription factor binding motifs.
