Receiver Device #1 -- ToxR
POC
wiki-Will
Function
To cause gene expression in the presence of input signal using the ToxR pathway.
Device Depiction
Information path ...
- Fluoroscein introduced to system (as Fluoroscein+DNAspacer+Fluoroscein), travels into periplasm.
- Fluoroscein binds to adjacent transmembrane ToxR'-scFv fusions .
- Causes ToxR' dimerization
- GFP expressed @ CTX_promoter
- As a function of ToxR dimerization
People path ...
- Maxine gives us Fluoroscein, or identifies something else
- Maxine's antigen binds to Jenny's scFv
- Then, Jenny's scFv induces Will's ToxR' to dimerize
- The dimerization leads to the expression of Jessica's output @ CTXpromoter [cI, maybe]
- Ray makes the whole system look like "we meant to do that."
- Jen makes sure it all works.
Device Parts
Current Status
- Ordered all necassary proteins and primers for first synthesis.
- Begin design and outline of necassary system experiments.
- Verify that we can get our signal into the periplasm
- Recieve oligo's 07/15. Lets throw them in our cells
- and if it doesn't "just work," develop and specify how we have to manipulate / weaken our cells to make it work.
- Properly document ordered parts on parts.mit
- Continue research on putting scFv onto outermembrane of cell.
Open Issues/Questions
- The periplasm
- Is the signal going in?
- Are our scFv's going to come out (to the surface)?
- Experimental issues (will = inexperience)
- people tend to be helpful .
