Abstract
|
|
|
Stabilization of protein-protein interactions (PPIs) holds great potential for
therapeutic agents, as illustrated by the successful drugs rapamycin and
lenalidomide. However, how such interface-binding molecules can be created in a
rational, bottom-up manner is a largely unanswered question. We report here how
a fragment-based approach can be used to identify chemical starting points for
the development of small-molecule stabilizers that differentiate between two
different PPI interfaces of the adapter protein 14-3-3. The fragments
discriminately bind to the interface of 14-3-3 with the recognition motif of
either the tumor suppressor protein p53 or the oncogenic transcription factor
TAZ. This X-ray crystallography driven study shows that the rim of the interface
of individual 14-3-3 complexes can be targeted in a differential manner with
fragments that represent promising starting points for the development of
specific 14-3-3 PPI stabilizers.
