We have used gel retardation and DNase protection assays to investigate the trans-acting factors involved in the regulation of yeast RNA polymerase genes RPC160 and RPC40. The same binding component was found to interact with the promoter of the two genes, at a short distance (100-150 base pairs) from the transcription start sites. From its size, its DNA-binding specificity and its immunological properties, this factor appears to correspond to the autonomous replication sequences and silencer-binding factor ABF1/SBF-B. The interaction of ABF1 with the polymerase upstream box sequence was characterized using gel DNA-binding assay. The factor binds with high affinity to the polymerase upstream box sequence (Kapp = 5.10(-10) M). A mutational analysis showed that nine base pairs belonging to two separated attachment sites are involved in factor binding. The consensus sequence RTCRYB(N)4ACG was derived from the present binding studies. These data provide an experimental basis for evaluating the efficiency of known or potential ABF1 sites and for comparing several factors with ABF1-like binding properties.
