Mapping of mass spectrometry hits and PAN-PCR products to retroviral genomes. Asterisks mark the position of peptides identified by mass spectrometry to be derived from pAMS-MLV (A) or SMRV (B), while grey bars indicate genomic regions highly homologous to PAN-PCR products. The hatched box (A) represents proviral sequences of pAMS with high sequence similarity to amphotropic MLV.
