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

Another step in the #Starship story - they move via a circular intermediate. Helps explain how these elements horizontally transfer and means that we can modify them into transformation vectors (starmids). www.biorxiv.org/content/10.6...
