HtrA1 Switch 28

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), GSGSG Linker (BBa_K4165066), TD28REV (BBa_K4165006), GGSGGGGG Linker (BBa_K4165019), WWW (BBa_K4165007), GSGSG Linker (BBa_K4165066), WAP inhibitor (BBa_K4165008), and T7 terminator (BBa_K731721).

Usage and Biology

Switch 28 is used to mediate the activity of HTRA1. It is composed of 3 parts connected by different linkers; an HtrA1 PDZ peptide, a clamp of two targeting peptides for tau or amyloid beta, and a catalytic domain inhibitor. 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 binding of affinity clamp to tau or beta-amyloid. This binding will result in a tension that detaches the inhibitor from the active site.

Modeling

The switch was modeled by (Alphafold - Rosettafold - tRrosetta) and the top model was obtained from Rossetafold with a score of 4 out of 6 according to our quality assessment code.
