Abstract

A family of highly repetitive elements, named LDT1, has been identified in the gypsy moth, Lymantria dispar. The complete element is 5.4 kb in length and lacks long-terminal repeats, The element contains two open reading frames with a significant amino acid sequence similarity to several non-LTR retrotransposons. The first open reading frame contains a region that potentially encodes a polypeptide similar to DNA-binding GAG-like proteins. The second encodes a polypeptide resembling both endonuclease and reverse transcriptase sequences. All members of the LDT1 element family sequenced thus far have poly-A tails or A-rich tails of 12-18 nucleotides in length, but lack a poly-A addition signal in the expected location.
