SYFPEITHI

SYFPEITHI catalogs experimentally verified peptide ligands and motifs for MHC class I and MHC class II molecules to support analysis of peptide-MHC interactions and T-cell epitope identification.

Key Features:

• Comprehensive Data Collection: A curated repository of MHC ligands and peptide motifs from humans and other species including apes, cattle, chickens, and mice, compiled from published reports.
• Search Functionality: Query capability by MHC allele, peptide motif, natural ligand, T-cell epitope, source protein or organism, and literature reference.
• Integration with External Databases: Cross-references and hyperlinks to EMBL and PubMed for linked genomic and bibliographic information.
• Predictive Capabilities: Includes ligand prediction tools for various MHC allelic products.

Scientific Applications:

• T-cell epitope identification: Support for identifying peptides presented by MHC class I and II molecules that may be recognized by T cells.
• Immunogenicity prediction: Use of known ligands and prediction tools to assess potential peptide immunogenicity.
• Vaccine design: Inform selection of candidate peptide epitopes for vaccine development based on MHC binding data.
• Antigen presentation research: Facilitate studies of antigen processing and MHC-peptide binding specificities.
• Comparative MHC analysis: Enable cross-species comparison of MHC ligands and peptide motifs.

Methodology:

Entries are manually curated from published scientific literature, linked to EMBL and PubMed, and the resource incorporates ligand prediction tools for MHC allelic products.
