The Nuclear Envelope brings together the major current topics in nuclear envelope structure, transport, transcriptional regulation and cell signaling. The volume is divided into four sections:1. Proteins of the nuclear envelope, including nuclear envelope proteomics, structure and function.2. Nuclear pores and transport at the nuclear envelope, including pore complex structure, assembly and function and import and export pathways.3. Nuclear envelope dynamics, including dynamics of lamina assembly and disassembly.4. Nuclear signaling and transcription regulation, including signaling to the nucleus and spectrin repeat proteins and their implications or communication between the nucleus and cytoplasm.
