PEPMatch

PEPMatch performs rapid peptide-to-proteome sequence matching using a deterministic k-mer mapping algorithm to identify conserved and putative epitope sequences for immunological research.

Key Features:

• Deterministic k-mer Mapping Algorithm: Preprocesses proteomes with a deterministic k-mer mapping approach, yielding up to 50-fold speed increases versus BLAST while maintaining high recall.
• Versatile Applications: Enables identification of conserved viral epitopes, putative allergen epitope targets, and cancer-associated neoepitopes.
• Benchmarking Framework: Was evaluated against a suite of existing methods using benchmarks tailored to peptide sequence matching to assess comparative performance.
• Scalability: The preprocessing approach is advantageous for handling large proteome datasets typical in immunological research.

Scientific Applications:

• Virology: Assessing epitope conservation across different viral strains.
• Allergen Research: Identifying potential allergenic epitopes.
• Oncology: Detecting cancer-associated neoepitopes to study tumor recognition and immune tolerance.
