Abstract
A human episomal sequence (HALF1) has been identified by its ability to restore expression of hepatic functions when used to transfect a rat dedifferentiated cell line. The genomic equivalent of this human episome (gHALF1) and its flanking sequences were analyzed. HALF1 itself does not present the characteristics of a transposable element but half of its sequence corresponds to retroposons, including Alu and L1 repeats and a processed pseudogene, known to transpose via RNA intermediates. The structural characteristics of these different kinds of retroposons and their origin and evolution were analyzed.
