10x[TALA+TALB] operator
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 for TALA and another ten for TALB. Single binding site is combined from 18 base pairs recognised by specific TAL.TALA and TALB binding sites are adjacent to each other making impossible for both of them to bind at once.
Single binding site sequence for TALA: TTTACTGCTGCTCCCGCT
Single binding site sequence for TALB: TCTTCCGTTTCCACATCT
Figure 1: Schematic representation of the construct.
Characterization
Construct was later used for constructing different reporter plasmids to show specific binding and competition between TALA and TALB.
