RNA transcripts of the HERV-R (ERV3) human provirus that are abundant in placenta but absent in choriocarcinoma contain nonproviral genomic sequences at their 3' ends. We report here the isolation of cDNA clones of these genomic sequences. The transcripts encode a Krüppel-related zinc finger protein consisting of a unique leader region and more than 12 28-amino-acid finger motifs.
