DoChaP: the domain change presenter.

Area of Science:

• Genomics
• Proteomics
• Bioinformatics

Background:

• Alternative splicing generates multiple mRNA transcripts from a single gene, potentially leading to protein isoforms with varying domain compositions.
• Manually analyzing alternative splicing's effect on protein domains is complex, error-prone, and impractical for large-scale studies.

Purpose of the Study:

• To develop an automated, user-friendly web server for visualizing exon-domain associations.
• To facilitate the study of alternative splicing's structural impact on protein domains at a genome-wide scale.

Main Methods:

• Development of the Domain Change Presenter (DoChaP) web server.
• Visualization of gene transcripts, encoded proteins, and their domain structures.
• Inclusion of comparative analysis between transcripts and protein products.
• Implementation of a two-species comparison for exon-domain association conservation.

Main Results:

• DoChaP provides intuitive visualization of how alternative splicing events alter protein domain composition.
• The tool enables easy identification of structural changes in proteins due to splicing variations.
• DoChaP supports the study of exon structure and alternative splicing conservation across species.

Conclusions:

• DoChaP offers a unique and accessible platform for exploring exon-domain associations and their conservation.
• The tool simplifies the investigation of alternative splicing's structural consequences in biological contexts, including disease states.
