Transcription activation like (TAL) effectors are bacterial plant pathogen transcription factors that bind to DNA by recognizing a specific DNA sequence in which each base pair binds a single tandem repeat in in the TAL DNA-binding domain. A tandem TAL repeat contains 33 to 35 amino acids, where the 12th and the 13th amino acid, called a “repeat variable diresidue” (RVD)  are responsible for specific interactions with the corresponding base pair (Scholze and Boch, 2011). All TAL repeats have almost identical sequences, differing only in the RVDs. This modularity of TAL effector binding domains therefore makes them a perfect tool to target specific DNA sequences by designing specific binding domains for a selected TAL effector. We designed twelve specific binding sites for TALD (Figure 1).

12x[TALD] operator

  • TALD label represents TAL effector 1295 from zebrafish experiments (Sander et al., 2011).
  • DNA binding sites for individual TAL effectors are indicated with square brackets [ ].


Introduction

TAL effectors (TALEs) are able to specifically bind to the DNA by recognizing base pairs on a DNA molecule. With TAL regulators we are able to control expression of a desired gene. Efficient transcription control can be achieved by binding of multiple TAL regulators upstream of promoter.

Our construct contain twelve specific binding sites for TALD (Figure 1).

Single binding sequence for TALD is: TCGTCCAATAGCTTCTC

  • Binding sites for TAL effectors were ordered from IDT.


Characterization

Construct was later used for constructing different reporter plasmids to show specific binding of TALD:KRAB/TALD:VP16.
