Small protein molecules almost do not experience the cytoplasm viscosity while moving within the cell. Scientists have now shown that the effect can be described universally to include ...

How do genes control us? This fundamental question still remains elusive despite decades of research. Genes are blueprints for proteins, but it is the proteins that actually carry out vital functions.

The nuclear pore is a protein-lined channel in the nuclear envelope that regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is separated ...

Over the past decade, there have been scattered reports of mammalian cells’ own DNA being found in the cytoplasm, mainly in the context of disease and aging. While it is not unusual to find DNA from ...

HuR, a ubiquitously expressed member of the Hu protein family that binds and stabilizes an AU-rich element (ARE)-containing mRNAs, is known to shuttle between the nucleus and the cytoplasm via several ...
