The existence of a growth-specific DNA binding factor for the promoter region of mouse ST2 gene
1994
Abstract A comparison of the 5′-flanking regions of human and mouse ST2 genes revealed the presence of two highly conserved DNA sequences. The promoter activity assay with a luciferase gene as a reporter showed that the deletion of the upstream conserved region diminished the transcriptional activity in growing BALB/c-3T3 cells. By electrophoretic mobility-shift analysis, the presence of a factor that binds to the positive regulatory region of the mouse ST2 gene was found in growing but not in quiescent BALB/c-3T3 cells. These results suggest the functional importance of this conserved region and the requirement of a binding factor for the expression of the ST2 gene.
