The ubiquitin-like molecule NEDD8 is essential for viability, growth and development, and is a potential target for therapeutic intervention. We found that the small molecule inhibitor of NEDDylation, ...

The size of a cell's nucleolus may reveal how long that cell, or even the organism it belongs to, will live. Over the past few years, researchers have been piecing together an unexpected link between ...

Biologists discovered that a scaffolding protein called TCOF1 is responsible for the formation of a biomolecular condensate called the fibrillar center, which forms within the cell nucleolus. Inside ...

The size of a cell's nucleolus may reveal how long that cell, or even the organism that cell belongs to, will live. Over the past few years, researchers have been piecing together an unexpected link ...

An essential component of living cells, the nucleolus underwent a major evolutionary shift around 300m years ago. Scientists have solved an age-old mystery in biology by discovering a protein found in ...

The nucleolus—a conspicuous but obscure organelle within the cell nucleus—is normally too compact to be studied in detail. Researchers at Case Western Reserve University just learned how to simplify ...

The nucleolus is a small organelle present in the nucleus of cells, which regulates physiologic processes such as growth and stress responses. Scientists from Cologne discovered that upon bacterial ...

Although known since the 1830s as a round, dark spot in a cell's nucleus, only recently has the nucleolus gotten its full due. Scientists have learned that besides building a cell's protein factories, ...

RNA, or ribonucleic acid, is a short-lived molecule copied from DNA that enables cells to use genetic information. Specific DNA sequences are copied into RNA, which then delivers these instructions to ...

Chinese scientists have made a fundamental breakthrough in the understanding of the nucleolus, a structure with important functions in the nucleus. Their findings may also pave the way for diagnoses ...
