Binds to DNA in a sequence-specific manner. The protein is composed of 27 tandem core repeats (the BuD domain) with 1 base-specifying residue (BSR, residue 13), which recognizes 1 base pair in the target DNA. By combining the DNA-binding domain with the catalytic domain of the restriction endonuclease FokI, TALE-nuclease (TALEN, or BuDN) enzymes able to target specific dsDNA sequences can be created that enable eukaryotic genome modification. Other potential uses as transcriptional repressors, for transposon targeting, DNA methylation or histone tail modifictions are also possible. DNA binding experiments were performed with a construct missing repeat 11. Belongs to the transcription activator-like effector (TALE) family. Bat subfamily.
