MER124 (DF0000721)

Unclassified, largely palindromic DNA transposon, MER124 subfamily

Description

Present in >500 copies in all mammals, including marsupials, but absent from platypus. The termini form a 108bp TIR. This palindrome possibly extends even further out. This large TIR does not match to any known DNA TIR. Note that MER stands for MEdium Reiteration frequency interspersed repeat. As such, MERs as a group are a grab bag of DNA transposons and retrotransposons.
