Cryo-EM structure of the Giardia ribosome reveals a highly compact, GC-rich rRNA with eukaryotic r-proteins. (A) Structure of the Giardia ribosome with all the r-proteins colored (SSU, shades of blue ...

In all eukaryotic organisms, genetic material is stored in the cell nucleus in the form of DNA. In order to be used, this DNA is first transcribed into messenger RNA in the cell cytoplasm, then ...

Many biological functions are regulated by the switching on and off of mechanisms triggered by the matching of a keyhole ...

A team of researchers has uncovered a previously unrecognized role of mitochondrial protein synthesis in the maintenance of intracellular iron distribution. Disruption of this process was found to ...

Research by UC Santa Cruz molecular biologist Harry Noller and his collaborators has led to the first direct observations of the mechanism for protein synthesis in living cells. Their new findings on ...

Neurons have a "hibernation mode." Scientists discover how brain cells use RNA tentacles to lock their protein factories together to survive when energy is low.

Before a newly synthesized protein can undergo folding, it must be processed and transported to the correct location within the cell after emerging from the ribosome. N-terminal acetylation ...

A new study from German researchers examines how SARS viruses, including the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), hijack cells and reprogram them to enhance viral replication.
