TALENs (Transcription Activator-Like Effector Nucleases)
TALENs (Transcription Activator-Like Effector Nucleases) presents a compelling scientific breakthrough with substantial patent protection, entering the critical pilot-scaling and regulatory proof-of-concept phase.
Scientific Foundation & Mechanism
Programmable gene-editing nuclease built by fusing engineered Transcription Activator-Like Effector (TALE) DNA-binding domains -- based on the simple one-repeat-per-base "TALE code" decoded independently by Boch et al. and Moscou & Bogdanove (2009) in the plant-pathogenic bacterium Xanthomonas -- to the FokI nuclease cleavage domain (Christian et al., Genetics, 2010; Miller et al., Nature Biotechnology, 2011). Easier to design than zinc finger arrays (one TALE repeat per target base, versus zinc fingers' context-dependent triplet recognition) and briefly overtook ZFNs as the leading customizable-nuclease platform around 2010-2012, commercialized by Cellectis and Life Technologies/Thermo Fisher. Still required assembling a large custom repeat-array protein per target site; CRISPR-Cas9's single, cheaply-synthesized guide RNA per target made TALENs largely obsolete for new projects within a few years of the 2012 Cas9 paper.
