Prediction and Comparative Analysis of MHC Binding Peptides and Epitopes in Nanoviridae Nano-organisms

Dangre DM, Deshmukh SR, Rathod DP, Umare VD and Ullah I

Nanoviridae is a family of single stranded DNA viruses which infect the plants through their phloem tissues. The few members of these viruses are now turning towards animals. It includes two genera, Nanovirus and Babuvirus. Nanovirus includes three species namely Faba beans necrotic yellows virus (FBNYV), Milk vetch dwarf virus (MVDV) and Subterranean clover stunt virus (SCSV) while Babuvirus have two species accounted yet, namely Abaca bunchy top virus (ABTV) and Banana bunchy top virus (BBTV). The viral coat proteins are likely to be responsible for many diseases in plants as well as animals. The intra-genomic changes or post translational modifications with in SCSV have decreased the length of the sequence, but increased the antigenic potential and numbers of antigenic binding regions on the surface of the protein. We have predicted the most probable responsible antigenic determinants and MHC binders within the viruses in Nanoviridae family. MHC molecules play a crucial role in host immune response. The nonamers of antigenic determinants in Nanoviridae family viral coat proteins are highly sensitive to H-2Kd and I-Ag7 molecules. The species within particular genera shows their common epitopes along with diverse colleague epitopes. These common antigenic peptides can be used as their identifi ers. These identifi ers along with their diverse colleagues could be most informative for antidotes production against themselves. Also, these are important for synthetic peptide vaccine production against the relevant viruses.
