Introduction

This part contains the protein COP1 fused to the Methyl-Tranferase G9a. It's an interaction partner of dCas9-UVR8 and part of the UVB light controlled mechanism to repress gene expression. You will be able to repress any desired gene by a short UV-light pulse.

Biology & Usage

COP1 is a protein that was first described in the model organism Arabidopsis thaliana. It will bind to the UV-light receptor UVR8 after illumination. Thereby recruiting G9a to its target locus. Subsequently the local DNA-expression will be repressed by DNA-methylation. For this UVB light controled gene repression system you need a combination of these BioBricks: Cas9-UVR8, COP1-G9a and RNaimer.
