We have analysed binding sites of nuclear protein factors to a CpG island (HTF9), which contains the promoter for a pair of overlapping, divergently-transcribed "housekeeping" genes. Using DNaseI protection assays with extracts from a range of differentiated and undifferentiated cell lines, including mouse embryonic stem (ES) and embryonal carcinoma (EC) cells, we located multiple protein binding sites on HTF9. Most of the sites were outside the defined core promoter and could bind to previously identified transcription factors...
