Abstract

Recent interest in inactive kinase conformations has generated the need to develop new biochemical tools to study them. Here, we describe the use of a fluorescent probe that selectively and potently binds to a specific inactive conformation of protein kinases. This allows for the thermodynamics and kinetics of ligand binding to be determined.

Key words

Kinase Inactive conformation DFG-out Activation loop Fluorescent probe Protein ligand Dissociation constant
