From: Corky, a gypsy-like retrotransposon is differentially transcribed in Quercus suber tissues
Organization and structure of Corky retrotransposon. (a) LTR, long terminal repeat; PR, protease; RVT, reverse transcriptase; R, RNAse H; INT, integrase; CH, chromatin organization modifier. PBS, primer binding site. PPT, polypurine tract. The entire element has a length of 5924 bp with 333 bp LTRs. (b) The terminal boxes at each end of Corky represent LTRs. The Target Site Duplications (TSD) of 7 bp direct repeat flanking Corky is shown. Above the element, the 5 bp inverted repeats (5’TGTTA…TAACA-3’) within each LTR are shown in the expansions. The primer binding site (PBS) and polypurine tract (PPT) are boxed. 14 nucleotides of the 3’ end initiator methionine tRNA complementary to the PBS region of Corky is shown.
