Researchers Find Tools Needed To Build a Cellular Shredder

(PhysOrg.com) -- Yale University researchers have discovered a set of cellular chaperones needed to assemble a proteasome, the cellular workhorse that recycles proteins and is crucial for the existence of all eukaryotic cells.

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.

A solid scaffolding for cells

To perform the task for which they have been synthesized, proteins must first assemble to form effective cellular "machines." But how do they recognize their partners at the right time? Researchers at the University of Geneva ...

Stem cells: Keeping differentiation in check

Researchers at the A*STAR Institute of Medical Biology (IMB) have discovered a critical checkpoint protein that controls when human embryonic stem cells (hESCs) begin to differentiate.

Scientists gain new insights into protein disposal

Cells have a sophisticated system to control and dispose of defective, superfluous proteins and thus to prevent damage to the body. Dr. Katrin Bagola and Professor Thomas Sommer of the Max Delbrück Center for Molecular Medicine ...
