Our understanding of protein export from the nucleus to the cytoplasm has been advanced
recently by the discovery of active, signal-mediated export pathways. Nuclear export signals …

Eukaryotic cells export several different classes of RNA molecule from the nucleus, where
they are transcribed, to the cytoplasm, where the majority participate in different aspects of …

Protein export from the nucleus of eukaryotic cells serves three main purposes:(1) to remove
factors that are only transiently required in the nucleus-transcriptional signaling molecules …

It has been appreciated for some time that basic-amino-acid-type nuclear localization
signals control nuclear uptake of proteins and that leucine-rich nuclear export signals …

One of the most profound differences between prokaryotes and eukaryotes is that only the
latter segregate RNA synthesis and protein synthesis into distinct cellular compartments, ie …

Transport of proteins, RNAs and ribonucleoprotein particles into and out of the nucleus is
essential for many cellular functions to proceed. Recent progress in this area of research …

▪ Abstract The compartmentation of eukaryotic cells requires all nuclear proteins to be
imported from the cytoplasm, whereas, for example, transfer RNAs, messenger RNAs, and …

The term nuclear transport, refers to the movement of a large variety of macromolecules both
into and out of the nucleus. Transport must be extremely selective, yet also very efficient. A …

Eukaryotic gene expression is controlled by multiple mechanisms, and its regulation is
central for physiological responses to extracellular and intracellular signals. An essential …

The presence of the nuclear envelope necessitates the movement of proteins and RNAs
between the nucleus and the cytoplasm. Elaborate cellular machinery exists to promote the …
