Reposted by Alex GaoSternberg Lab @sternberglab.bsky.social · 12/05/20261/9 New preprint from the Sternberg Lab in collaboration with the Nishimasu Lab! We uncover how the DRT3 antiphage immune system pairs two reverse transcriptases, one RNA-templated and one protein-templated, to build a double-stranded DNA effector. doi.org/10.64898/202... 27028
Alex Gao @algao.bsky.social · 19/04/2026Great summary by @philipcball.bsky.social! Our findings certainly don’t invalidate the central dogma, but rather demonstrate an unexpected (and cool!) structural mechanism by which a sequence-specific DNA is created in a cell. (1/6) 26819
Alex Gao @algao.bsky.social · 16/04/2026Excited to share our new findings in @science.org on how the DRT3 bacterial defense system uses a reverse transcriptase that builds DNA repeats without a nucleic acid template. Microbes never cease to amaze! www.science.org/doi/10.1126/...science.orgScience | AAAS 412460
