TraPS-VarI: Identifying genetic variants altering phosphotyrosine based signalling motifs

Area of Science:

• Genomics
• Immunology
• Bioinformatics

Background:

• Individual genotypes are increasingly available, but interpreting mutations in transmembrane proteins, especially in immune cells, lags behind.
• These transmembrane proteins are crucial targets for cancer immunotherapy, with signaling properties dependent on specific sequence motifs.
• Mutations altering these motifs can impact cellular signaling, yet remain largely uncharacterized.

Purpose of the Study:

• To develop a tool for identifying mutations in transmembrane proteins and their impact on signaling motifs.
• To facilitate the interpretation of genotype-specific alterations in immune cell transmembrane proteins.
• To support personalized therapeutic strategies in cancer immunotherapy.

Main Methods:

• Development of the Transmembrane Protein Sequence Variant Identifier (TraPS-VarI) algorithm.
• Creation of a web interface and database browser for TraPS-VarI.
• Annotation of transmembrane protein sequences to map mutation effects and identify signaling motifs.

Main Results:

• TraPS-VarI accurately maps the effects of individual mutations in transmembrane protein sequences.
• The tool identifies the prevalence of critical signaling motifs (TBSMs) affected by mutations.
• A user-friendly web interface and database browser are available for TraPS-VarI.

Conclusions:

• TraPS-VarI provides a valuable resource for biologists and clinicians to interpret genetic variations in transmembrane proteins.
• Understanding mutation-driven alterations in immune cell signaling is essential for advancing cancer immunotherapy.
• This tool aids in patient stratification and the development of individualized therapeutic strategies.
