New findings shed light on the repair of UV-induced DNA damage

An international research team has clarified the regulatory mechanism of the ubiquitin-proteasome system in recognizing and repairing DNA that has been damaged by ultraviolet (UV) light. The investigators at Kobe University ...

Hitchhikers hinder medication shelf life

Why some biopharmaceuticals have a longer shelf life than others is a problem that has baffled scientists and manufacturers alike. Even the same medication, produced by different manufacturers, can vary in its storage life.

The birth and death of proteins in a single cell

The amount of proteins inside cells fluctuates over time, and this affects various functions of the cells. Cells are constantly synthesizing and degrading proteins, and studies have shown that this "see-saw" effect actually ...

How cells take out the trash—phosphoarginine deciphered

Cells never forget to take out the trash. It has long been known that cells tag proteins for degradation by labelling them with ubiquitin, a signal described as "the molecular kiss of death". Tim Clausen's group at the Research ...

Successful recycling: Protein quality control in the cell

A team led by MDC researcher Annika Weber has pinpointed the efficient mechanism used by cells to label faulty proteins. The findings, which provide important insights into the functioning of protein quality control in the ...
