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-loop that is critical for their retrotransposition found in their 3′ end.
The UnaL2 LINE 3′ element is a conserved RNA structure integral to the UnaL2 LINE (long interspersed nuclear element) and SINE (short interspersed nuclear element) of eel. This structural motif, situated at the 3′ end, is vital for their retrotransposition mechanism.
