Abstract:
Separation of DNA replication and transcription, which occur in the nucleus, from protein synthesis, which occurs in the cytoplasm, allows a more precise regulation of these processes. Selective exchange of macromolecules between the two compartments is mediated by proteins of the nuclear pore complex (NPC). Receptor proteins of the karyopherin family interact with NPC components and transfer their cargos between the nucleus and cytoplasm. Nucleocytoplasmic transport pathways are regulated at multiple levels by modulating the expression or function of individual cargoes, transport receptors, or the transport channel. The regulatory levels have increasingly broad effects on the transport pathways and affect a wide range of processes from gene expression to development and differentiation.

Regulation of Nuclear Protein Sorting
Nuclear Protein Sorting
Proteins targeted to the nucleus carry nuclear localization signals or NLS recognized by import receptors in the cytosol. Similarly, proteins with nuclear export signals are recognized by export receptors. Import and export receptors are...

Overview of Protein Sorting and Transport
Protein sorting can be of two types: signal-based sorting and vesicle-based trafficking. In signal-based sorting, specific amino acid sequences called sorting signals target proteins to the proper location inside the cell either via gated transport or by protein translocation. In gated transport, folded...
