HtrA1 Switch number 12

This composite part consists of T7 promoter (BBa_K3633015), lac operator (BBa_K4165062), pGS-21a RBS (BBa_K4165016), 6x His-tag (BBa_K4165020), SPINK8 Inhibitor (BBa_K4165010), GS Linker (BBa_K4165017), seed peptide (BBa_K4165012), GS Linker (BBa_K4165019), seed peptide (BBa_K4165012), GS Linker (BBa_K4165017), H1A (BBa_K4165000) and T7 terminator (BBa_K731721).


Usage and Biology

Switch 12 is used to mediate the activity of HTRA1. Activating HTRA1 requires a conformational change in the linker, eliminating the attached inhibitor from the active site. The conformational rearrangement can be mediated through the affinity clamp for tau and beta-amyloid binding. These clamps are used for stabilizing the inhibitor away from the active site. These two domains (inhibitor and affinity clamp connected with linker1). Additionally, (H1A) binding peptide bound to the PDZ domain and connected to the affinity clamp on the other side with linker3
