question: What induces downstream of gene (DoG) readthrough transcription?
answer: Stress-induced transcriptional readthrough generates very long downstream of gene containing transcripts (DoGs), which may explain up to 20% of intergenic transcription. Massive induction of transcriptional readthrough generates downstream of gene-containing transcripts (DoGs) in cells under stress condition. Ca2+ signaling mediates reduced transcription termination in response to certain stress conditions. This reduction allows readthrough transcription, generating a highly inducible and diverse class of downstream of gene containing transcripts (DoGs) that we have recently described.
