Protein Domain·Research·Since 2023

Also known as: inactive NS3 protease

Taxonomy: Mechanism Branch / Component. Workflows sit above the mechanism and technique branches rather than replacing them.

Summary

Catalytically inactive NS3 protease is a protein domain repurposed as a high-affinity binder for genetically encoded antiviral peptides. In the reported system, peptide-bound NS3 complexes are displaced by FDA-approved NS3-targeting drugs to chemically control transcription, cell signaling, split-protein complementation, and allosteric Cre recombinase regulation.

Usefulness & Problems

Why this is useful

This tool enables chemical control of engineered protein functions through a drug-displaceable protein–peptide interaction rather than catalytic activity. It is useful for building regulatable systems that respond to clinically relevant NS3-targeting antivirals and for creating orthogonal recombination control in eukaryotic cells and across divergent organisms.

Source:

Allosteric Cre regulation with NS3 ligands enables orthogonal recombination tools in eukaryotic cells and functions in divergent organisms to control prokaryotic recombinase activity.

Problem solved

It addresses the need for a genetically encoded, chemically actuated interaction module that can switch protein activities using small molecules. Specifically, it provides a new mechanism for allosteric regulation of Cre recombinase and supports control of transcription, signaling, and split-protein outputs through drug displacement.

Implementation is based on domain fusion using catalytically inactive NS3 protease together with genetically encoded antiviral peptides. Chemical input is provided by FDA-approved NS3-targeting drugs that displace the NS3–peptide complex; the evidence does not specify the exact NS3 variant, peptide sequence, or construct architecture.

The supplied evidence does not report quantitative binding, dynamic range, kinetics, or comparative performance against alternative chemically controlled interaction systems. Practical constraints such as drug-specific potency, background binding, construct size, and context dependence are not described in the provided evidence.
