Abstract:
SINE-FR1A is one of at least 2 SINE families in Fugu rubripes that consist of a tRNA derived polymerase III promoter region followed by a sequence homologous to the mammalian DNA transposon family MER6. This combination is currently particular to fish and named 'Mermaid' after one of the first described elements. Usually, the 3' end of a SINE corresponds to the 3' end of a local LINE-like element, on which element the SINE is dependent for transposition. However, no LINE with a MER6-type 3' end has been described so far, and we did not find any in Fugu either. The function of the MER6 unit is currently unclear Bases 1-75 are tRNA derived, resembling SINE_AF of cychlids. Bases 181-306 (end) are similar to MER6. A SINE_FR1-like SINE is found in Perch as well. The average substitution level of copies is 12% (2 subfamilies).
