Inside all living cells, loosely formed assemblies known as biomolecular condensates perform many critical functions. However, it is not well understood how proteins and other biomolecules come ...

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 ...

A nucleolar protein, nucleostemin, is now implicated in the control of stem and cancer cell proliferation. Nucleostemin may modulate p53 function through shuttling between the nucleolus and the ...

The nucleolus is the site of ribosome biosynthesis, but is now known to have other functions as well. In the present study we have investigated how the distribution of signal recognition particle (SRP ...

New research has advanced understanding of how the nucleolus is assembled through a process called liquid-liquid phase separation and has identified a protein that plays key role Researchers have ...

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, ...

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 ...

Striking nucleolar lesions occur in cultured cells after exposure to supranormal temperatures. These lesions appear at 42°C and consist of a loss of the granular ribonucleoprotein (RNP) component and ...

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 ...
