By electrophoresis mobility shift assays using probes corresponding to different segments of the putative human c - myb intron 1 transcription pause region and nuclear extracts from myeloid leukemia HL 60 and fibroblast WI 38 cells , we detected a HL - 60 - specific DNA - protein complex with a 123 - bp fragment containing binding sites for the interferon regulatory factors ( IRFs ) nuclear proteins .
