Transcriptional regulation of genes comprises a multistep process. It starts with the activation of one or more transcription factors in the cell cytoplasm, movement of the transcription factor(s) into the nucleus, and binding to its associated DNA consensus sequence, which initiates the transcription of specific genes. This plays an important role in regulating inflammatory and autoimmune responses, cell proliferation and apoptosis.
Activation of transcription factors can be monitored by imaging as a translocation from the cytoplasm to the nucleus using antibodies for the transcription factors or fluorescent protein tags.
