2x[NicTAL]+2x[TALD] operator

  • TALD label represents TAL effector 1295 from zebrafish experiments (Sander et al., 2011).

Introduction

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 two consecutive specific binding sites for NicTAL12 and TALD (Figure 1).

Single binding sequence for NicTAL12 is: TCTATCAATGATAGA

Single binding sequence for TALD is: TCGTCCAATAGCTTCTC

  • Binding sites for TAL effectors were ordered from IDT.
