UnaL2 LINE 3' element
The UnaL2 LINE 3' element is an RNA element found in the UnaL2 LINE (
long interspersed nuclear element) and partner SINE ( short interspersed nuclear element) from eel. This conserved element is a stem-loopthat is critical for their retrotransposition found in their 3' end. The first step of retrotransposition is the recognition of their 3' tails by UnaL2-encoded reverse transcriptase. The NMRstructure of a 17- nucleotideRNA derived from the 3' tail of UnaL2 has been determined.
