title: Characterization of the 5'-regulatory region of rat Reg I gene.
abstract: We report here the characterization of the 5'-regulatory region of rat Reg I gene encoding a growth stimulating factor for pancreatic beta-cells. Transient expression assays of the 5'-flanking region/luciferase fusion gene in AR4-2J cells showed that the -304/-237 region contained positive cis-acting elements. Gel shift assays using AR4-2J and rat pancreas nuclear extracts showed the formation of a specific complex with the -256/-237 oligonucleotide.
