Abyss1: a novel L2-like non-LTR retroelement of the snakelocks anemone (Anemonia sulcata).
Cytogenet Genome Res. 2005; 110(1-4):553-8.CG

Abstract

Non-LTR retrotransposons are a diverse and taxonomically widely dispersed group of retroelements that can be divided into at least 14 distinguishable clades. Basal metazoans have not been examined in great detail for their retrotransposon content. In order to screen for the presence of reverse transcriptase (RT) related sequences in Cnidaria and Ctenophora, basal phyla of metazoans, PCR with highly degenerate oligonucleotides was performed and an RT-like sequence was identified from the sea anemone species Anemonia sulcata. Further screening identified a related element in another anemone species Actinia equina. Significant homology to non-LTR retrotransposon RTs was observed, particularly to L2-like elements of fish such as Maui. The sequence was not detected among other cnidarians and we have designated the A. sulcata and A. equina elements Abyss1 and Abyss2 respectively. Phylogenetic analysis of Abyss1 compared with members of 14 known non-LTR retroelement clades suggests that the sequence represents a novel L2 element.
