It seems to repress gene expression by having red light inhibit phosphorylation which would activate a promoter. I don't understand how pops affects this at all...

After looking at some devices, it would seem as POPS has to do with the RBS. So... a device with a weak strength is activated by high POPS...? I'm just guessing here now... And i don't understand how the chemical signals won't diffuse to affect other promoters.. or will it?
