title: Chromosomal localization and sequence analysis of a human episomal sequence with in vitro differentiating activity.
abstract: The genomic fragment carrying the human activator of liver function, previously described as an episome capable of inducing differentiation upon transfection into a dedifferentiated rat hepatoma cell line, was mapped on human chromosome 12q24.2-12q24.3. This chromosomal location was indistinguishable by in situ hybridization from that of the gene coding for the hepatic transcription factor HNF1. The sequence of the integrated form of the episome as well as its flanking sequences show that it is rich in retroposons. It contains a human ribosomal protein L21 processed pseudogene, one truncated L1Hs sequence, and 10 Alu repeats, which belong to different subfamilies.
