Preprint alert 🚨: We built a CRISPRi screen for a part of the genome that is unusually awkward to perturb: the RNA Pol III transcriptome. Hundreds of tRNA genes, lots of sequence similarity, plenty of redundancy... Turns out the biology had a few surprises for us 👇 www.biorxiv.org/content/10.6...

Thrilled to see this published today! Truly special because we made the initial discovery >15 yrs ago! We found two copies of a human gene called BC200 embedded in a human poxvirus. BC200 blurs the line between gene & transposon—both functional & mutagenic! www.science.org/doi/10.1126/... 🧵1/n
