Mapping the Dynamics of the Glucocorticoid Receptor within the Nuclear Landscape
The distribution of the transcription machinery among different sub-nuclear domains raises the question on how the architecture of the nucleus modulates the transcriptional response. Here, we used fluorescence fluctuation analyses to quantitatively explore the organization of the glucocorticoid rece...
