10x[TALB] operator

• TALB and TALC labels represents TAL effector 1297 and 1259 from zebrafish experiments (Sander et al., 2011).

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 ten binding sites while single binding site is combined from 18 base pairs specificly recognised by TALB.

Single binding site sequence for TALB: TCTTCCGTTTCCACATCT

Binding sites are constructed in alternating setup. Besides TALB binding sites construct also contain ten alternating TALC binding sites, which we didn't use, since TALC regulator wasn't working properly.

Characterization

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