BIAPSS: A Comprehensive Physicochemical Analyzer of Proteins Undergoing Liquid-Liquid Phase Separation

Area of Science:

• Biochemistry
• Molecular Biology
• Bioinformatics

Background:

• Liquid-liquid phase separation (LLPS) is a fundamental cellular process driving the formation of membraneless organelles.
• The relationship between protein primary sequences and LLPS propensity is not well understood.
• Identifying sequence-encoded signals for LLPS is crucial for understanding cellular organization.

Purpose of the Study:

• To develop a novel bioinformatics tool for analyzing protein sequences involved in LLPS.
• To provide insights into the sequence-encoded signals that govern LLPS.
• To facilitate the study of biomolecular condensates and membraneless organelles.

Main Methods:

• Development of a web platform named BIAPSS (Bioinformatics Analysis of LLPS Sequences).
• Curated a comprehensive dataset of proteins known to undergo LLPS.
• Implemented on-the-fly analysis of physicochemical and structural features of LLPS proteins.

Main Results:

• BIAPSS enables rapid analysis and visualization of sequence features related to LLPS.
• The platform facilitates the interpretation of how protein sequences dictate phase separation behavior.
• Provides a valuable resource for researchers studying the molecular basis of LLPS.

Conclusions:

• BIAPSS is a novel web server for the bioinformatics analysis of LLPS sequences.
• The platform aids in uncovering sequence-encoded signals governing LLPS.
• Facilitates research into the biogenesis of membraneless organelles and cellular bodies.
