Figure 7From: Lineage specific evolution of the VNTR composite retrotransposon central domain and its role in retrotransposition of gibbon LAVA elementsDeterminants of LAVA mobilization efficiency are localized in the VNTR. (A) Schematic representation of the LAVA_E – LAVA_F chimeras tested. 5’ and 3’ domains of LAVA_E and LAVA_F were reciprocally exchanged at the Alu-like/VNTR junction and/or the VNTR/3’ part junction. Note that LAVA_F elements are characterized by a 3’ truncated Alu-like region. (B) Retrotransposition reporter assay following selection with G418. Cells were co-transfected with driver (pJM101 L1RP Δ Neo) and the respective mneoI-tagged chimeras or the LAVA_E/LAVA_F full-length constructs. Retrotransposition rates (+/− standard deviation, n = 3) are given relative to that of the full-length LAVA_F1 construct (100%). (C) Repeat unit (RU) schemata of the two LAVA elements tested. RU arrays corresponding to the respective subfamily consensus are highlighted in grey.Back to article page
