Specific nuclear localizing sequence directs two myosin isoforms to the cell nucleus in calmodulin-sensitive manner. [PDF]
BACKGROUND: Nuclear myosin I (NM1) was the first molecular motor identified in the cell nucleus. Together with nuclear actin, they participate in crucial nuclear events such as transcription, chromatin movements, and chromatin remodeling.

Nuclear dynamics: Formation of bodies and trafficking in plant nuclei
The existence of the nucleus distinguishes prokaryotes and eukaryotes. Apart from containing most of the genetic material, the nucleus possesses several nuclear bodies composed of protein and RNA molecules.

Recent ultrastructural studies revealed that a structure similar to the vertebrate nuclear lamina exists in the nuclei of higher plants. However, plant genomes lack genes for lamins and intermediate-type filament proteins, and this suggests that plant ...

Polylysine (pLy) has been used successfully as a DNA carrier in receptor-mediated gene transfer, enhancement of transfection having been proposed to be in part through efficient nuclear targeting stemming from the resemblance of pLy to the nuclear localization sequence (NLS) from simian virus SV40 large tumor antigen (T-ag).

Replication of the RNA genome of influenza A virus occurs in the nucleus of infected cells. The influenza nucleoprotein (NP) associated with the viral RNA into ribonucleoprotein complexes (vRNPs) is involved in the nuclear import of the viral genome.

Identification of a Bipartite Nuclear Localization Sequence Necessary for Nuclear Import of 5-Lipoxygenase [PDF]
5-Lipoxygenase catalyzes the synthesis of leukotrienes from arachidonic acid. This enzyme can reside either in the cytoplasm or the nucleus; its subcellular distribution is influenced by extracellular factors, and its nuclear import correlates with changes in leukotriene synthetic capacity.

Diffusion of Proteins Across the Nuclear Envelope of HeLa Cells
We describe an experimental system to study nucleocytoplasmic diffusion of proteins in living HeLa cells. To localize proteins to the nucleus, substrates were created that contain a nuclear localization sequence fused to Aequorea victoria green ...

The Nuclear Localization of Glycogen Synthase Kinase 3β Is Required Its Putative PY-Nuclear Localization Sequences [PDF]
Glycogen synthase kinase-3β(GSK-3β), which is a member of the serine/threonine kinase family, has been shown to be crucial for cellular survival, differentiation, and metabolism. Here, we present evidence that GSK-3β is associated with the karyopherin β2 (Kap β2) (102-kDa), which functions as a substrate for transportation into the nucleus. A potential

The Ebola Virus Interferon Antagonist VP24 Undergoes Active Nucleocytoplasmic Trafficking
Viral interferon (IFN) antagonist proteins mediate evasion of IFN-mediated innate immunity and are often multifunctional, with distinct roles in viral replication.

Nuclear Targeting of the Maize R Protein Requires Two Nuclear Localization Sequences [PDF]
Previous genetic and structural evidence indicates that the maize R gene encodes a nuclear transcriptional activating factor. In-frame carboxyl- and amino-terminal fusions of the R gene to the reporter gene encoding beta-glucuronidase (GUS) were sufficient to direct GUS to the nucleus of the transiently transformed onion (Allium cepa) epidermal cells ...
