Abstract
We have characterized the genomic structure of the mouse Zfp148 gene encoding Beta-Enolase Repressor Factor-1 (BERF-1), a Kruppel-like zinc finger protein involved in the transcriptional regulation of several genes, which is also termed ZBP-89, BFCOL1. The cloned Zfp148 gene spans 110 kb of genomic DNA encompassing the 5′-end region, 9 exons, 8 introns, and the 3′-untranslated region. The promoter region displays the typical features of a housekeeping gene: a high G+C content and the absence of canonical TATA and CAAT boxes consistent with the multiple transcription initiation sites determined by primary extension analysis. Computer-assisted search in the human genome database allowed us to determine that the same genomic structure with identical intron–exon organization is conserved in the human homologue ZNF 148. Functional analysis of the 5′-flanking sequence of the mouse gene indicated that the region from nucleotide -205 to +144, relative to the major transcription start site, contains
