New steps toward the nucleocytoplasmic traffic of macromolecules.
The nucleocytoplasmic transport of functional molecules is mediated bidirectionally through the nuclear pore complex (NPC), which spans the double membranes of the nuclear envelope. It has recently been shown that signaling between the nucleus and the cytoplasm plays a key role in coordinating the cellular processes such as the cell cycle and cell differentiation (Yoneda, 2000). As the result of recent extensive analysis, significant progress has been made in our understanding of the fundamental mechanism of nuclear transport of proteins and RNAs and numerous transport factors have now been identified. In this special issue of review articles, we focus on our rapid growing knowledge of nucleocytoplasmic transport, especially the translocation of proteins through the NPC and mRNA export, and review this exciting field from various points of view including cell biology, structural biology and yeast genetics.
