From Selfish Transposon Enzymes to Programmable Miniature Genome Editors: The Biology, Evolution, and Engineering of TnpB Nucleases

Sanchit Pal Singh, Shruti Gupta, Rohit Solanki, Vivek Singh & Amritanshu Upadhyay · Journal of Advances in Biology & Biotechnology · 2026

TnpB proteins are among the most abundant genes encoded in bacterial and archaeal genomes, yet their function in the transposon life cycle remained unclear for decades. Recognition that TnpB is the likely evolutionary ancestor of type V CRISPR-Cas12 effector nucleases, followed b...
