Part:BBa_K1965051

Myc:nLuc:GS6:TEVs:GS6:AP4

This construct consists of the N-terminal part of the split luciferase that is fused to the AP4 coiled coil (1) via a linker which contains the cleavage substrate for TEV protease. The construct also contains the Myc tag on the N-terminus. The AP4 coiled coil dimerizes with the P3 coiled coil. If its partner coiled coil (P3) contains the C-terminal part of the split luciferase, then dimerization of the two coils enables luciferase reconstitution due to the close proximity of the split luciferase parts. However, because the linker contains TEV protease cleavage substrate, the nLuc can be cleaved off in the presence of the TEV protease, preventing reconstitution of the split luciferase (2).

Sequence alignment of different coils used to tune the affinity of antiparallel coiled-coils.
We designed different destabilized coils from our coiled coil pair AP4 and P3; Ile and Leu were substituted with Ala at the a and/or d position of the first and/or second heptad of P3mS (a more soluble variant of the original P3).

Introduction of protease cleavage site between the reporter (effector) and coiled-coil segment(s).
Cleavage sites in between CCs and reporter protein introduces logical negation.
