Nups take leave of the nuclear envelope to regulate transcription.

ABSTRACT

Although components of the nuclear pore complex have been implicated in gene regulation independent of their role at the nuclear envelope, the evidence so far has been indirect. Capelson et al. (2010) and Kalverda et al. (2010) now reveal that certain nucleoporins are actively involved in transcription inside the nucleoplasm of Drosophila cells.
