Targeting protein conformations with small molecules to control protein complexes.

Area of Science:

• Biochemistry
• Molecular Biology
• Structural Biology

Background:

• Dynamic protein complexes are crucial for cellular functions like signaling and transcription.
• Protein conformational switching regulates activity via interactions, catalysis, localization, or membrane binding.
• Understanding these dynamics is key to cellular regulation.

Purpose of the Study:

• To review recent examples of small molecules modulating conformationally dynamic proteins.
• To highlight rational design strategies for discovering protein modulators.
• To emphasize the potential of small molecules in protein oligomerization control.

Main Methods:
