From: Contribution of type W human endogenous retroviruses to the human genome: characterization of HERV-W proviral insertions and processed pseudogenes

Fig. 1

Overview on the HERV-W structural completeness. The presence of each retroviral element in the three classes of HERV-W sequences is depicted. An element is considered as retained if at least the 20 % of the sequence is present (lengths are referred to LTR17-HERV17 reference elements). With respect to the LTR17 RepBase consensus (780 nucleotides), proviral sequences show complete LTRs, while processed pseudogenes present typically truncated LTRs due to the L1-mediated retroposition, lacking U3 in 5′ LTR (R-U5 structure, nucleotides 256–780) and U5 in 3′ LTR (U3-R structure, nucleotides 1–326)
