Notes: This paper describes a method for using bioluminescence resonance energy transfer (BRET) to reveal the binding characteristics of a drug with selected targets in live cells. The authors used cell-permeable fluorescent tracers in a competitive binding assay to quantify drug engagement with target proteins fused to Nanoluc luciferase. Using this approach, they were able to profile isozyme-specific engagement and binding kinetics for a panel of histone deacetylase (HDAC) inhibitors. (4587)
