Part:BBa_K4165060

HtrA1 Switch 40

This composite part consists of T7 promoter (BBa_K3633015), lac operator (BBa_K4165062), pGS-21a RBS (BBa_K4165016), 6x His-tag (BBa_K4165020), H1A (BBa_K4165000), GS Linker (BBa_K4165064), seed peptide (BBa_K4165012), GS Linker (BBa_K4165019), seed peptide (BBa_K4165012), GS Linker (BBa_K4165064), WAP inhibitor (BBa_K4165008), and T7 terminator (BBa_K731721).

Usage and Biology

This part performs a multifunction role in our system, the Plug-Sink system. The H1A (BBa_K4165000) peptide directs the whole peptide to bind to the PDZ HtrA1 protein (BBa_K4165004). The second part is the binding peptide which directs the whole peptide-HtrA1 complex to the tau (BBa_K4165009) and amyloid (BBa_K4165005) aggregates. The last part makes the whole system switch on or off based on the presence of the target protein, thus part is the WAP inhibitor (BBa_K4165008).
