Abstract excerpt

The first high resolution maps of the Xenopus laevis ribosomal promoter and its flanking regions (-179 to +14) have been created by assaying point mutants both in oocyte and in vitro. Within the promoter boundaries (-141(-145) to +3(+4)), domains analogous to the Core Promoter and "Upstream Control Element" (UCE) were clearly detected. The base pairs at -133, within the UCE, and -20, -10, -7, and +3, within the...
