Extended Data Fig. 3: CIP-1 ternary complex structural analysis.
From: DNA-encoded library-enabled discovery of proximity-inducing small molecules
(a) Six copies of the ternary complex are present in each asymmetric unit. An overlay of the six ternary complexes shows the structures are highly similar with RMS deviations of 1.06–1.37 Å. (b) The electron density for CIP-1 is well defined in 4 of the 6 complexes of the asymmetric unit. 2Fo – Fc maps contoured at 2.5σ and 1σ are shown for CIP-1 in a ternary complex with well-defined density. (c) BRD4BD1 protein surface with residues colored based on interactions with CIP-1 (blue), VHL (red), or both (purple). CIP-1 is shown in sticks. (d) VHL protein surface with residues colored based on interactions with CIP-1 (blue), BRD4BD1 (red), or both (purple). (e) 2D diagram of CIP-1 interactions with BRD4BD1. (f) 2D diagram of CIP-1 interactions with VHL.
