Epstein-Barr virus proteins were examined for amino acid sequence matching to human proteins at the decapeptide level. We report that numerous EBV peptides of different length (from 10- to 13-mer) are present in 28 human proteins. The viral versus human peptide overlap mainly involves the glycine-rich region allocated in the NH2-terminus of Epstein-Barr nuclear antigen 1 protein and host cellular components that play crucial roles in basic biochemical pathways, such as chromatin remodelling, RNA splicing, transmission across chemical/electrical synapses, neurogenesis, and that, when altered, may characterize various pathologies such as immunodeficiency, systemic lupus erythematosus, myelination, and speech disorders. The present results might contribute to understand and define the (physio)pathological relationships and interactions occurring between EBV and the human host.
