But there are other types of proteins called transcription factors, and they have specific interactions with DNA. (scientificamerican.com)
The team then introduced these synthetic proteins back into the cell to see which specific interactions would restore the stem cell's transformative abilities. (sciencedaily.com)
In the experiments just reported, these highly specific interactions are situated in the context of a larger global network regulating the fear response in mice. (sciencedaily.com)
