Bioactivity Comments
Ligand ET binds to WT BRD2(1) and BRD2(2) with Kds of 9 and 17 µM respectively. In line with the experimental hypothesis, ET displayed much lower Kds against the corresponding L/A mutants [BRD2(1)L110A and BRD2(2)L383A] which represents 9120- and 200-fold stronger binding relative to WT. Actual Kds for the mutants are 74 and 86 nM [1]. respectively.
