I also had the opportunity to contribute to an interesting nanopore sequencing project led by my colleagues Jenny Vo and Logan Mulroney. Using SMIT I was able to demonstrate that Jenny and Logan’s new approach to enzymatically attach a tail on inosines onto a pool of cellular RNAs in yeast could be used to detect nascent transcripts undergoing transcription. This work was published in the journal RNA (Vo et al. 2021).
Here we see nanopore sequencing results from different sequencing libraries. Chromatin associated RNAs are from the nuclear fraction and are enriched for nascent RNAS. Here you can see the yeast actin gene has many different 3' ends as it is being made and co-transcriptionally spliced!
