Abstract:
Long interspersed nuclear elements 1 (L1) are active retrotransposons that reside in many species, including humans and rodents. L1 elements produce an RNA intermediate that is reverse transcribed to DNA and inserted in a new genomic location. We have tagged an active human L1 element (L1 RP ) with a gene encoding enhanced GFP (EGFP). Expression of GFP occurs only if L1-EGFP has undergone a cycle of transcription, reverse transcription, and integration into a transcriptionally permissive genomic region. We show here that L1-EGFP can undergo retrotransposition in vivo and produce fluorescence in mouse testis. The retrotransposition event characterized here has occurred at a very early stage in the development of an L1-EGFP transgenic founder mouse.
