Abstract:
This family was active several million years ago: copies of REX1-3_XT are ~98% identical to the consensus sequence. The 3' terminus is composed of the (TCTA)n microsatellite. There is a 82% identity between the complete 3548-bp frog REX1-3_XT and 3394-bp zebrafish REX1-1_DR consensus sequences. Threfore, horizontal transfer was involved in evolution of these two families of non-LTR retrotransposons.Interestingly, the RT domain in these two families and some other REX1 families, including REX1-4_XT, REX1-6_XT and REX1-8_XT, is followed by the pfam09004 domain conserved in diverse eukaryotic proteins.
