Abstract excerpt
Using transgenic mice, we have identified a human CD4 silencer contained within a 484-bp fragment in the first intron of the CD4 gene. Further experiments have mapped a lineage-specific silencing activity to a region of 190 bp. This region contains two protein-binding sites detected by deoxyribonuclease I footprinting analyses. Tested in transient transfection assays, these two DNA elements showed significant...
