Abstract: Copia4_TP is a young family of Copia-like LTR retrotransposons. Copia4-I_TP, an internal portion of Copia4_TP is flanked by 99% identical Copia4-LTR_TP LTRs. There is no tRNA-like primer binding site in Copia4_TP. Instead, this retrotransposon uses self-priming by the 12-bp TACTTCGAAGTA palindrome present at the very 5'-end of its internal portion. The internal portion encodes the 328-aa Copia4_TP1p gag (pos. 191-1131) and 1319-aa Copia4_TP2p pol (pos. 1132-5088), respectively. Copia4_TP1p includes RING Zn-finger, 39% identical to a similar motif in gag (NC) encoded by Rous sarcoma avian retrovirus. Copia4_TP2p is composed of the protease, integrase, reverse transcriptase and ribonuclease H domains.
