| abstractText | Beta2/neuroD is a basic helix-loop-helix protein involved in differentiation of the endocrine pancreas and the central nervous system. A 2-kb fragment containing the 5' upstream region of the mouse beta2/neuroD gene was cloned and sequenced. The cloned fragment was tested for promoter activity in six cell lines. Strong promoter activity was apparent in the three pancreatic beta cell lines, beta-HC3, beta-HC9, and NIT-1, whereas weak activity was seen in NIH 3T3, Rat-1, and MCF-7 cell lines. Analysis of promoter activity of deletion mutants in beta-HC3 cells indicated that while basal promoter activity was observed with a fragment which extended -109 bp upstream of the transcription start site, maximal activity required the fragment -2091 to -297 bp. |
