KinCon: Cell-based recording of full-length kinase conformations

Area of Science:

• Biochemistry
• Molecular Biology
• Pharmacology

Background:

• Kinase alterations require mutation-oriented therapeutic strategies.
• Challenges in tracking kinase activity hinder drug discovery.
• Non-catalytic kinase functions involve conformation changes.

Purpose of the Study:

• Introduce the extendable kinase conformation (KinCon) reporter toolbox.
• Enable live-cell recording of kinase states and conformation dynamics.
• Facilitate drug discovery for kinase and pseudokinase regulation.

Main Methods:

• Utilizing a genetically encoded bioluminescence-based biosensor platform.
• Measuring conformation dynamics of mutated kinases.
• Assessing small molecule inhibitor effects on kinase states.

Main Results:

• KinCon allows functional annotation of kinase activities beyond phospho-transfer.
• The toolbox can record conformation changes of kinases in live cells.
• Potential to delineate molecular mechanisms of kinase regulation.

Conclusions:

• KinCon reporter toolbox offers a novel approach for studying kinase conformation dynamics.
• This platform can accelerate the discovery of specific and effective kinase inhibitors.
• Expands drug discovery efforts towards full-length kinase-targeted therapies.
