with reference to protein accession numbers: HERV-K10 Gag2 (Capsid and Nucleocapsid) (AAA88031.1), Pol/Env (AAA88033.1), IgG Fc (AF150959). Residues highlighted in
bold indicate amino acid substitutions. Alignment score shown as number of identical residues/number in peptide segment. Amino acid replacement score taken from Tudos [19
Amino acid single letter code: G=Glycine, A=Alanine, S=Serine, T=Threonine, C=Cysteine V=Valine, D=Asparate, E=Glutamate N=Asparagine, Q=Glutamine, P=Proline,
K=Lysine, H=Histidine, Y=Tyrosine. Despite a low scoring amino acid replacement for A to V, the overall molecular shape could remain similar enough to enable antibody cross-reactivity.
