Complete Genome of XMRV

(A) Schematic map of the 8185 nt XMRV genome. LTR regions (R, U5, U3) are indicated with boxes. Predicted open reading frames encoding Gag, Gag-Pro-Pol, and Env polyproteins are labeled in green. The corresponding start and stop codons (AUG, UAG, UGA, UAA) as well as the alternative Gag start codon (CUG) are shown with their nt positions. Similarly, splice donor (SD) and acceptor (SA) sites are shown and correspond to the spliced 3.2-Kb Env subgenomic RNA (wiggled line).

(B) Cloning and sequencing of XMRV VP35 and VP62 genomes. Clones obtained by probe recovery from hybridizing microarray oligonucleotides (blue bar) or by PCR from tumor cDNA (black bars) were sequenced. Primers used to amplify individual clones (Table S2) were derived either from the genome of MTCR (black arrows) or from overlapping VP35 clones (blue arrows).

(C) Genome sequence similarity plots comparing XMRV VP35 with XMRV VP42, XMRV VP62, MuLV DG-75, MTCR, and a set of representative non-ecotropic proviruses (mERVs) (see Materials and Methods). The alignments were made using AVID [81], and plots were generated using mVISTA [82] with the default window size of 100 nt. _Y_-axis scale for each plot represents percent nt identities from 50% to 100%. Sequences are labeled as xenotropic (X), polytropic (P), or modified polytropic (Pm).
