Intrinsically disordered proteins and liquid-liquid phase separation in drug discovery.

Area of Science:

• Biochemistry and Molecular Biology
• Cell Biology
• Drug Discovery

Background:

• Intrinsically disordered proteins (IDPs) are crucial for cellular organization via liquid-liquid phase separation (LLPS).
• IDPs' dynamic nature enables the formation of biomolecular condensates (BCs), essential for biological processes.
• Dysregulation of LLPS by IDPs is implicated in diseases like cancer and neurodegeneration.

Purpose of the Study:

• To explore the role of IDPs and LLPS in cellular organization and disease.
• To review emerging therapeutic strategies targeting IDP-driven phase separation.
• To highlight challenges and future directions in modulating condensate behavior for treatment.

Main Methods:

• Review of current literature on IDPs, LLPS, and disease mechanisms.
• Analysis of novel therapeutic approaches, including small molecules, peptides, and PROTACs.
• Discussion of computational methods and AI in understanding IDP conformational landscapes.

Main Results:

• IDPs' conformational flexibility drives LLPS, forming functional BCs.
• Aberrant LLPS contributes to various pathologies, presenting therapeutic targets.
• Diverse strategies, from physicochemical modulators to targeted protein degradation, are being developed.

Conclusions:

• Targeting IDP-mediated LLPS offers a promising avenue for novel therapeutics.
• Overcoming challenges in IDP heterogeneity and condensate variability is key.
• Integrated advances in technology are essential for developing next-generation therapies.
