A molecular hammock for cotranslational modification

Proteins do most of the real work in cells and are modified in accordance with functional requirements. An LMU team has now shown how proteins are chemically altered on the ribosome, even before they fold into the active ...

Biologists show inner workings of cellular 'undertaker'

One of a cell's most important responsibilities is to break down and recycle proteins that are no longer needed or endanger the cell. This task is carried out by a cellular nanomachine called the proteasome.

Cryo-electron microscopy characterizes integrins

A collaboration between three labs at UC San Francisco has resulted in an unprecedented look at a member of a vital and ubiquitous class of proteins called integrins (pronounced "INT-uh-grins"). Integrins are associated with ...
