The nuclear envelope
SpletThe nuclear pore complex (NPC) mediates selective transport across the nuclear envelope (NE) and plays crucial roles in several additional cellular functions. In higher eukaryotes, the NPC and the NE disassemble and reassemble during cell division and live-cell imaging has been a powerful tool to analyze these dynamic processes. Here, we ...
