Gibbs Sampling Shows Possibilities of B-Cell Epitope Signatures
We have attempted finding common sequential patterns among protein antigens. For this, we have used Gibbs multiple motif sampler on the set of all non-redundant antigenic sequences available in curated databanks. Several sequential motifs are obtained on these sequences when the amino acids are represented according to their similarity clusters. Significantly high proportions of known B-cell epitope sites are found within or adjacent to these motifs, thus indicating a possibility of linear epitope signatures. These findings may offer important applications in synthesis of peptide vaccines. A predictive example in this regard is presented.

More about this publication?
- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
