Abstract

The elements comprising the mouse rpS16 promoter were characterized by transfection experiments with mutant genes in which various portions of the 5' flanking region and exon I were removed or substituted with extraneous DNA sequence. These experiments were carried out with otherwise intact rpS16 genes transfected into monkey kidney (COS) cells and also with chimeric rpS16-CAT gene constructs transfected into mouse plasmacytoma cells and COS cells. The locations of the functionally important elements were generally correlated with the locations of binding sites for specific nuclear factors, which were identified by gel-mobility shift analyses and methylation interference footprints. The most upstream element, which is located approximately 165 bp from the cap site, binds the Sp1 transcription factor and augments the promoter activity by 2 to 2.5-fold. In addition, there is a complex bipartite element in the -83 to -59 region, an element in the -37 to -12 region and an element in the +9 to +29 region of exon I, all of which are essential for rpS16 expression. The rpS16 promoter has a general architecture that resembles other mouse rp promoters; however, it also possesses some distinctive characteristics.
