ProSAS: a database for analyzing alternative splicing in the context of protein structures

Area of Science:

• Molecular Biology
• Structural Biology
• Bioinformatics

Background:

• Alternative splicing is a key mechanism generating functional diversity in eukaryotes.
• Splicing isoforms are implicated in critical cellular processes such as apoptosis and signal transduction.
• While mRNA-level splicing events are documented, their direct impact on protein structure remains largely unexplored.

Purpose of the Study:

• To address the gap in understanding splicing's effect on protein structure.
• To introduce the ProSAS database as a unified resource for analyzing alternative splicing in the context of protein structures.

Main Methods:

• Development of the ProSAS database, integrating Ensembl and SwissProt data.
• Annotation and modeling of protein structures for entries with splicing events.
• Creation of a user-friendly interface for structure-based analysis of alternative splicing.

Main Results:

• ProSAS provides comprehensive annotations and structural models for proteins affected by alternative splicing.
• The database enables analysis of alternative isoforms at both protein structure and function levels.
• Features tools for intuitive, structure-based investigation of alternative splicing impacts.

Conclusions:

• The ProSAS database effectively links alternative splicing events to protein structural information.
• It serves as a valuable resource for researchers studying the functional consequences of alternative splicing.
• Facilitates a deeper understanding of how splicing variations influence protein architecture and cellular roles.
