10x[TALB] operator_minimal promoter

• 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 TALB binding sites and minimal promoter.

Minimal promotor is taken from pGL4 vector series (promotor is described [http://www.promega.com/~/media/files/resources/protocols/technical%20manuals/0/pgl4%20luciferase%20reporter%20vectors%20protocol.pdf?la=en here] on the page 18).

Single binding site is combined from 18 base pairs specificly recognised by TALB. Binding sites are constructed in alternating setup. Besides TALB:VP16 binding sites construct also contain ten alternating TALC:VP16 binding sites, which we didn't use, since TALC:VP16 regulator wasn't working properly.

Single binding site sequence for TALB: TCTTCCGTTTCCACATCT
