Protein Databases Related to Liquid-Liquid Phase Separation.

Area of Science:

• Biochemistry and Molecular Biology
• Cell Biology
• Biophysics

Background:

• Liquid-liquid phase separation (LLPS) is crucial for forming membraneless organelles (MLOs) or biomolecular condensates.
• LLPS regulates diverse physiological processes and is implicated in disease development.
• Recent research intensifies focus on LLPS functions, drivers, and regulatory mechanisms within cells.

Purpose of the Study:

• To systematically compare six major databases related to LLPS and MLOs.
• To evaluate data content, annotations, organization, and unique features of these resources.
• To guide researchers in selecting appropriate databases for studying biomolecular phase separation.

Main Methods:

• Comparative analysis of six LLPS-related databases (LLPSDB, PhaSePro, PhaSepDB, DrLLPS, RNAgranuleDB, HUMAN CELL MAP).
• Evaluation of database content, annotation depth, and structural organization.
• Identification of overlaps, differences, and specific applications for each database.

Main Results:

• Databases vary in data scope, annotation detail, and organizational structure.
• Key differences and overlaps among the six databases were identified.
• Unique features of each database were highlighted, indicating specific use cases.

Conclusions:

• These databases provide invaluable resources for understanding LLPS and MLOs.
• The comparative analysis aids in selecting optimal tools for biomolecular condensate research.
• These resources support advancements in phase-separating protein prediction and design.
