Abstract:
EXPANDER1_DR is a family of RTE-like non-LTR retrotransposons and it was active in zebrafish a few million years ago. There are several thousand copies of EXPANDER1_DR fossilized in the zebrafish genome; they are ~91% identical with the consensus sequence. The 5' portion of EXPANDER1_DR is incomplete. The consensus encodes a 3' portion of the reverse transcriptase. EXPANDER1_DR is 87% identical to EXPANDER1 from the fugu genome. Such a high nucleotide identity between non-LTR retrotransposons from the species diverged more than 100 million years ago strongly indicates that horizontal transfer events were involved in evolution of EXPANDERs.
