MHCPEP--a database of MHC-binding peptides: update 1995

Area of Science:

• Immunology and Bioinformatics
• Molecular Biology

Background:

• Major Histocompatibility Complex (MHC) molecules play a crucial role in the adaptive immune system by presenting peptide antigens to T cells.
• Understanding peptide-MHC interactions is fundamental for deciphering immune responses and developing targeted therapies.
• Existing data on peptide-MHC binding is often scattered across various publications and formats.

Purpose of the Study:

• To create a comprehensive, curated database of peptide sequences known to bind MHC molecules.
• To facilitate research in immunology and bioinformatics by consolidating critical experimental data.
• To provide a searchable resource for peptide-MHC binding information.

Main Methods:

• Compilation of peptide sequences and associated MHC binding data from published literature.
• Inclusion of experimentally determined data, including peptide sequence, MHC specificity, and binding affinity.
• Data curation from direct submissions of experimental results.

Main Results:

• Development of MHCPEP, a database containing over 6000 peptide sequences with known MHC binding specificities.
• Each entry includes detailed information such as peptide sequence, MHC specificity, experimental methods, binding affinity, and source protein.
• The database is accessible via the internet and designed for text string matching searches.

Conclusions:

• MHCPEP serves as a valuable, centralized resource for researchers studying peptide-MHC interactions.
• The database format is amenable to integration with sequence analysis tools for advanced research.
• Accessibility via Gopher, FTP, and WWW enhances its utility for the scientific community.
