Abstract: Copia1_TP is a young family of Copia-like LTR retrotransposons. Copia1-I_TP, an internal portion of Copia1_TP is flanked by 100% identical Copia1-LTR_TP LTRs. The consensus sequence encodes the 1506-aa Copia1_TPp polyprotein (positions 89-4606) composed of the protease, integrase, reverse transcriptase and ribonuclease H domains. Copia1_TP is characterized by unusual 6-bp target site duplications (5-bp in standard Copia-like elements). There is no tRNA-like primer binding site in Copia1_TP. Instead, this retrotransposon uses self-priming by the 12-bp CGTTTATAAACG palindrome present at the very 5'-end of its internal portion.
