Efficient expression of genes under the control of alpha-amylase 2 5'-flanking sequences in exocrine pancreatic cells requires, in addition to the pancreas transcription factor 1 binding site (M. Cockell, B.J. Stevenson, M. Strubin, O. Hagenbüchle, and P. K. Wellauer, Mol. Cell. Biol. 9:2464-2476, 1989), another cis-acting element at positions -60 to -86. This DNA element, which contains an AT-rich core, site for nuclear proteins present not only in the pancreas but also in other tissues and cell lines derived from the endoderm. Purification of binding activities from pancreatic cells by DNA affinity chromatography reveals several distinct proteins ranging in size from 45 to 54 kDa (p45, p47/48, and p54). All of these proteins interact with the specific DNA sequence upon renaturation in vitro. Protein sequencing, electrophoretic mobility shift assay, and immunoblot analyses identify p54 and p47/48 as members of the hepatocyte nuclear factor 3 (HNF3 [forkhead]) family of transcription factors. p54 belongs to the subfamily of HNF3 beta proteins, while p47/48 binding activity includes HNF3 gamma. The cDNAs for two HNF3 beta proteins differing only in N-terminal amino acid sequences were isolated from a pancreatic cDNA library. The mRNAs encoding the two protein species accumulate to different steady-state levels in poly(A)+ RNA of pancreatic cells. Our results support a model by which the pancreas-specific expression of the alpha-amylase gene is mediated by a combination of cell-specific and cell lineage-specific transcription factors.
