From: Classification and characterization of human endogenous retroviruses; mosaic forms are common
Unrooted phylogram of Pol consensus sequences (“con”, magenta) of canonical and best representatives (“bre”; brown) of some noncanonical proviruses together with reference Pols from GenBank (with Genbank id, black), and previous work by the authors (“2-con” were previous consensus sequences). Pol sequences were aligned with Muscle. A maximum likelihood tree was calculated. The asterisks mark the three supergroups which contain RepBase clades belonging to RepBase group MER4I
