Organizing a cell's genetic material from the sidelines

A tremendous amount of genetic material must be packed into the nucleus of every cell—a tiny compartment. One of the biggest challenges in biology is to understand how certain regions of this highly packaged DNA can be ...

Nanodiscs catch misfolding proteins red-handed

When proteins misfold, accumulate and clump around insulin-producing cells in the pancreas, they kill cells. Now, researchers, including University of Michigan biophysicists, have obtained a structural snapshot of these proteins ...

Chromosome mechanics guide nuclear assembly

Every one of our cells stores its genome within the nucleus – the quintessential subcellular structure that distinguishes eukaryotic cells from bacteria. When animal cells divide, they disassemble their nucleus, releasing ...

How packing away DNA stabilizes cell fate decisions

Susan Gasser and her group at the FMI have identified in C. elegans a much sought-for anchor protein, a previously uncharacterized chromodomain protein called CEC-4 that directly sequesters inactive chromatin at the nuclear ...

Nuclear membrane repairs the 'dark matter' of DNA

Scientists have found a new function of the nuclear membrane, the envelope that encases and protects DNA in the nucleus of a cell - it fixes potentially fatal breaks in DNA strands.

Putting the squeeze on a cell's nucleus

Nuclear membranes protect genes—life's most precious cargo—but little is known about why they function in different tissue types. For instance, nuclei in brain cells tend to be soft and pliable while those in bone cells ...
