Targeting protein disorder: the next hurdle in drug discovery

Area of Science:

• Biochemistry and Molecular Biology
• Cellular Biology
• Drug Discovery

Background:

• Intrinsically disordered proteins (IDPs) play crucial roles in cellular signaling and regulation.
• Dysregulation of IDPs is linked to various diseases, including cancer, neurodegeneration, inflammation, and autoimmune disorders.
• Targeting IDPs is essential for treating diseases driven by transcription, biomolecular condensation, and protein aggregation.

Purpose of the Study:

• To review key developments in understanding and targeting intrinsically disordered proteins.
• To highlight the challenges posed by the dynamic and heterogeneous nature of IDPs in drug discovery.
• To propose a synergistic approach combining experimental and computational methods for IDP-targeted drug development.

Main Methods:

• Review of current literature on intrinsically disordered proteins.
• Analysis of advanced experimental techniques for studying IDP dynamics.
• Evaluation of computational approaches for modeling IDP conformational ensembles.

Main Results:

• IDPs are characterized by heterogeneous, dynamic structural states and rapidly interconverting conformations.
• Traditional drug discovery approaches have largely considered IDPs 'undruggable' due to their structural plasticity.
• Recent advancements offer new possibilities for characterizing and targeting IDPs.

Conclusions:

• A combination of cutting-edge experimental and computational strategies is necessary to overcome the challenges in targeting IDPs.
• Synergistic approaches are crucial for developing effective therapeutics against diseases involving IDPs.
• The 'undruggable' nature of IDPs can be conquered through integrated research efforts.
