Active transport between the nucleus and cytoplasm involves primarily three classes of
macromolecules: substrates, adaptors, and receptors. Some transport substrates bind …

▪ Abstract The leptotene/zygotene transition of meiosis, as defined by classical cytological
studies, is the period when homologous chromosomes, already being discernible …

NLS proteins are transported into the nucleus by the importin α/β heterodimer. Importin α
binds the NLS, while importin β mediates translocation through the nuclear pore complex …

The assembly of eukaryotic ribosomal subunits takes place in the nucleolus and requires
nuclear import of ribosomal proteins. We have studied this import in a mammalian system …

Synthetic phytochelatin-related peptides are used as an organic coat on the surface of
colloidal CdSe/ZnS semiconductor nanocrystals synthesized from hydrophobic coordinating …

Eukaryotic cells are equipped with a machinery charged with the responsibility of
transporting a vast number of molecules in and out of the nucleus in a rapid, accurate, and …

The phytochrome (phy) family of plant photoreceptors controls various aspects of
photomorphogenesis. Overexpression of rice phyA–green fluorescent protein (GFP) and …

RanGAP1 is the GTPase-activating protein for Ran, a small ras-like GTPase involved in
regulating nucleocytoplasmic transport. In vertebrates, RanGAP1 is present in two forms …

Although many viruses replicate in the nucleus, little is known about the processes involved
in the nuclear import of viral genomes. We show here that in vitro generated core particles of …

Major advances have recently occurred in our understanding of GATA factor-mediated,
nitrogen catabolite repression (NCR)-sensitive gene expression in Saccharomyces …
