tetR-Pif6 for yeast


Usage and Biology

The TetR (tetracyclin Repressor) is originally found in bacteria and encodes natively for tetracycline resistance. [1] In scientific use it is usually fused to VP16 from herpes simplex virus, which acts as a transactivator and recruits RNA Polymerase to express the related gene. [2] TetR binds the tetO motiv in the construct upstream of a promoter and the gene(s). [3]

PIF6 is fused to tetR that binds the tetO motif in the designed construct upstream of a minimal promoter and the designed construct/gene. PIF6 is the interacting factor or Phytochrome B (PhyB), which is a photoreceptor from Arabidopsis thaliana. When Phy B is activated with red light it can be recruited and bound to PIF6. [4]


Biobrick in combination with PhyB-VP16: In red light, PhyB-VP16 is recruited to PIF6 at the promoter site, which activates the expression of the genes. Upon absorption of far red light the interaction of Phyb and PIF6 is terminated, resulting in silencing of the gene. [5]
