title: Nuclear proteins from Capan-2 cell line form specific complexes with the 17-1A antigen gene promoter.
abstract: To determine the location of sites important for the function of the 17-1A antigen gene promoter and to characterize the protein factors binding to these sites, fragments of the promoter region were analysed by gel retardation assay with nuclear extracts from Capan 2 cell line. At least two separate regions, which specifically bind nuclear proteins, were identified within the 5'flanking region of the 17-1A antigen gene. These regions have been located between nucleotides -877 to -518 (distal region) and -193 to +3 (proximal region) and presumably participate in regulation of expression of the 17-1A antigen gene.
