Usage and Biology
Switch 22 plays a role in mediating HTRA1's function. For HTRA1 to become active, a conformational modification in the linker is necessary, which displaces the associated 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 beside with amyloid beta binding peptide connected to tau binding peptide by linker 2). Additionally, (H1A) binding peptide bound to the PDZ domain and connected to the affinity clamp on the other side with linker3.
