MINERVa consensus sequence annotation. The annotation is based on sequence similarities to other deltaretroviruses; the splice sites were predicted using the NNSPLICE 0.9 algorithm (www.fruitfly.org/seq_tools/splice.html); results with score >0.80 are shown. The 3′ part of putative gag ORF with undetectable homology was not annotated. ORFs 1/2 do not begin with start codons because 5′ ends of deltaretroviral accessory genes are known to be located in a distant region of the proviral genome and intact ORFs are formed by splicing.
