Nuclear transport and transcription.

摘要

The compartmentalization of DNA in the nucleus of eukaryotic cells establishes a connection between the nuclear transport machinery and the transcriptional apparatus. General transcription factors, as well as specific transcriptional activators and repressors, such as p53 and NF-AT, need to be imported into the nucleus following their translation. In addition, nuclear transport plays a crucial role in regulating the activity of many transcription factors.
