Bacterial ribosomes are central to protein synthesis, and their regulation is vital for adaptation to environmental stresses. Under conditions such as nutrient deprivation, cold shock or hypoxia, ...

Now, scientists at the University of Illinois Chicago are the first to report a method for stable attachment of peptides to tRNAs, which has allowed them to gain new fundamental insights into ribosome ...

Under stress, animal cells pair inactive ribosomes into RNA-linked disomes. A ribosomal RNA “kissing loop” joins them, protecting ribosomes and reducing protein synthesis to conserve energy.<br /> ...

Ribosomes are fundamental molecular machines that translate mRNA sequences into polypeptides, ensuring the proper synthesis of proteins essential to cellular function. However, the fidelity of protein ...

Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...

A new technique reveals ribosome cooperativity, providing new insights into protein production. Researchers from Marvin Tanenbaum’s group at the Hubrecht Institute (Utrecht, Netherlands) have ...

These spots are socRNAs being translated by ribosomes in a cell. They get brighter over time, showing active translation. The complex, which includes the socRNA and ribosome, is attached to the plasma ...

Aging leads to a decline in cellular fitness and loss of optimal protein function. The mechanisms underlying how aging causes proteins to aggregate have not been fully understood. Using models of ...

Inside tiny cellular machines called ribosomes, chains of genetic material called messenger RNAs (mRNAs) are matched with the corresponding transfer RNAs (tRNAs) to create sequences of amino acids ...

Because ribosomes function as protein makers, they are also crucial to the survival of fast-growing tumor cells. Several classes of cancer drug already work by slowing ribosome formation in one way or ...

Research finds that the cellular assembly line that produces proteins can stall with age, triggering a snowball effect that increases the output of misfolded proteins. In humans, clumps of misfolded ...
